This basically represents the same information as
sc->recv_io.reassembly.queue_length.
The only thing that's different is that
smbd_connection.count_reassembly_queue was updated in each
loop step, while sc->recv_io.reassembly.queue_length is only
updated once after the loop in smbd_recv.
Also sc->recv_io.reassembly.queue_length is updated under
a spinlock.

We setup the first timer with the negotiate timeout and set
KEEP_ALIVE_PENDING, so that the expired timer disconnects.
On every incoming message we need to reset the timer to the keepalive
interval (120s).
On SMBDIRECT_FLAG_RESPONSE_REQUESTED we need to schedule a response
instead of setting KEEP_ALIVE_PENDING. Doing both would mean
we would also set SMBDIRECT_FLAG_RESPONSE_REQUESTED in that
response. If both ends would do that we'd play ping pong in
a busy loop.
If we move to KEEP_ALIVE_SENT and send the keepalive request
with SMBDIRECT_FLAG_RESPONSE_REQUESTED, we need to setup the
timer with keepalive timeout (5s) in order to disconnect
if no incoming message reset the timer.
The fired timer sets KEEP_ALIVE_PENDING and also
setup timer with keepalive timeout (5s) in order to disconnect
if no incoming message reset the timer.
We do that before queueing the send_immediate_work
and have that timer in case we didn't reach the send code
that typically sets the timer to keepalive timeout.

(At least for me) the logic maintaining the count of posted
recv_io messages and the count of granted credits is much easier
to understand.
From there we can easily calculate the number of new_credits we'll
grant to the peer in outgoing send_io messages.
This will simplify the move to common logic that can be
shared between client and server in the following patches.

We already call ib_drain_qp() before, which is an sync operation
that only returns in the queues are fully drained.
ib_drain_qp() completes pending requests with IB_WC_WR_FLUSH_ERR
so we have already called put_receive_buffer().
So all smbdirect_recv_io objects are either in the
smbdirect_socket.recv_io.free.list or
smbdirect_socket.recv_io.reassembly.list.
Then we explicitly iterate smbdirect_socket.recv_io.reassembly.list
and call put_receive_buffer(), so every object is
in smbdirect_socket.recv_io.free.list.
It means info->count_receive_queue == sp->recv_credit_max was
already true and calling wait_event(info->wait_receive_queues...
is pointless.

This is already handled in the server, but currently it done
in a very complex way there. So we do it much simpler.

If we're already disconnecting we don't need to queue the
disconnect_work again. disable_work() turns the next queue_work()
into a no-op.
Also let smbd_destroy() cancel(and disable) queued disconnect_work and
call smbd_disconnect_rdma_work() inline.
The makes it more obvious that disconnect_work is never queued
again after smbd_destroy() called smbd_disconnect_rdma_work().
It also means we have a single place to call rdma_disconnect().
While there we better also disable all other [delayed_]work.

wake_up_interruptible[_all]() doesn't wake up tasks waiting
with wait_event().
So we better wake_up[_all]() in order to wake up all tasks in order
to simplify the logic.
As we currently don't use any wait_event_*_exclusive() it
doesn't really matter if we use wake_up() or wake_up_all().
But in this patch I try to use wake_up() for expected situations
and wake_up_all() for situations of a broken connection.
So don't need to adjust things in future when we
may use wait_event_*_exclusive() in order to wake up
only one process that should make progress.
Changing the wait_event_*() code in order to keep
wait_event(), wait_event_interruptible() and
wait_event_interruptible_timeout() or
changing them to wait_event_killable(),
wait_event_killable_timeout(),
wait_event_killable_exclusive()
is something to think about in a future patch.
The goal here is to avoid that some tasks are not
woken and freeze forever.
Also note that this patch only changes the existing
wake_up*() calls. Adding more wake_up*() calls for
other wait queues is also deferred to a future patch.

We can use the state change from
SMBDIRECT_SOCKET_RESOLVE_{ADDR,ROUTE}_RUNNING
to the next state in order to wake the caller to do the next step.

We can use the state change from SMBDIRECT_SOCKET_NEGOTIATE_RUNNING to
SMBDIRECT_SOCKET_CONNECTED or SMBDIRECT_SOCKET_NEGOTIATE_FAILED in order
to notify the caller if the negotiation is over.

For the reader it is not obvious that the counter values are displayed
in hex as there's no leading '0x' before '%x'.
So changed them to %u instead and added '0x' for non-counter values
and also a string for the status.
Note this generates some checkpatch warnings like this:
WARNING: quoted string split across lines
#45: FILE: fs/smb/client/cifs_debug.c:460:
+ seq_printf(m, "\nSMBDirect protocol version: 0x%x "
+ "transport status: %s (%u)",
But I'll leave this is the current style in the
related code...

This will be used when a connected conection gets the first error.

This will be used to turn SMBDIRECT_SOCKET_CONNECTED into an
error within smbd_disconnect_rdma_connection() on the client
and smb_direct_disconnect_rdma_connection() on the server.
We do this in a single commit with the client as otherwise it
won't build because the enum value is not handled in the
switch statement.

The process of reaching a functional connection represented by
SMBDIRECT_SOCKET_CONNECTED, is more complex than using a single
SMBDIRECT_SOCKET_CONNECTING state.
This will allow us to remove a lot of special variables and
completions in the following commits.
