Quinn Tran 41e5afe51f scsi: qla2xxx: Fix exchange oversubscription 
In large environment, it is possible to experience command timeout and
escalation of path recovery. Currently the driver does not track the number
of exchanges/commands sent to FW. If there is a delay for commands at the
head of the queue, then this will create back pressure for commands at the
back of the queue.

Check for exchange availability before command submission.

Fixes: 89c72f4245 ("scsi: qla2xxx: Add IOCB resource tracking")
