No more need in a blk-mq world where the scsi command and request are

Pull SCSI updates from James Bottomley:
"This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
xfcp, hisi_sas, cxlflash, qla2xxx.
In the absence of Nic, we're also taking target updates which are
mostly minor except for the tcmu refactor.
The only real core change to worry about is the removal of high page
bouncing (in sas, storvsc and iscsi). This has been well tested and no
problems have shown up so far"

During an uplink toggle test all error handling is done via timeout and
firmware error conditions which can occur concurrently:
- SCSI layer timeouts
- Error detect CQEs
- Firmware detected underruns
- ABTS timeouts
All these concurrent events require more defensive checks in the driver
including:
- Check both internally and externally generated aborts to make sure the
xid is not already been aborted in another context or in cleanup.
- Check back pointers in qedf_cmd_timeout to verify the context of the
io_req, fcport and qedf_ctx
- Check rport state in host reset handler to not reset the whole host
if the rport is already uploaded or in the process of relogin
- Check to state for an fcport before initiating a middle path ELS
request

There are a couple of kernel cases when we restart a remote port due to
ABTS timeout that we need to handle:
1. Flush any outstanding ABTS requests when flushing I/Os so that we do
not hold up the eh_abort handler indefinitely causing process hangs.
2. Check if we are currently uploading a connection before issuing an
ABTS.

We need to check that a fcport is offloaded before we try to flush any
requests. No doing so could lead to undefined results and most likely a
crash.

Pointer fcport is initialized with a value that is never read, it is
re-assigned a new value later on, hence the initialization is redundant
and can be removed.

Modify core driver (qed) to utilize the new FW and initialize the device
with it. This is the lion's share of the patch, and includes changes to FW
interface files, device initialization flows, FW interaction flows, and
debug collection flows.
Modify Ethernet driver (qede) to make use of new FW in fastpath.
Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath.
Modify FCoE driver (qedf) to make use of new FW in fastpath.
Modify iSCSI driver (qedi) to make use of new FW in fastpath.

This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.
It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.
In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

Based on an original patch by Hannes Reinecke.
The driver didn't follow the atomic_t vs refcount_t change, and anyway
one should be using kref_read() instead of accessing the counter inside
an kref.
