Using sysfs's xprt_state attribute, mark a particular transport offline.
It will not be picked during the round-robin selection. It's not allowed
to take the main (1st created transport associated with the rpc_client)
offline. Also bring a transport back online via sysfs by writing "online"
and that would allow for this transport to be picked during the round-
robin selection.

sunrpc: add add sysfs directory per xprt under each xprt_switch2021-07-08T18:03:23ZOlga Kornievskaiakolga@netapp.com2021-06-08T19:59:18Zurn:sha1:d408ebe04ac58eb370e2d264e88edbab746adda6
Add individual transport directories under each transport switch
group. For instance, for each nconnect=X connections there will be
a transport directory. Naming conventions also identifies transport
type -- xprt-<id>-<type> where type is udp, tcp, rdma, local, bc.

sunrpc: add a symlink from rpc-client directory to the xprt_switch2021-07-08T18:03:23ZOlga Kornievskaiakolga@netapp.com2021-06-08T19:59:17Zurn:sha1:2a338a543163ad6b42f4732396249cea6d3a33c8
An rpc client uses a transport switch and one ore more transports
associated with that switch. Since transports are shared among
rpc clients, create a symlink into the xprt_switch directory
instead of duplicating entries under each rpc client.
