[SCSI] qla2xxx: Add checks for a valid fcport in dev-loss-tmo/terminate_rport_io callbacks.
Commit f78badb1ae07e7f8b835ab2ea0b456ed3fc4caf4 ([SCSI] fc
transport: pre-emptively terminate i/o upon dev_loss_tmo timeout)
changed the callback semantics of dev_loss_tmo and
terminate_rport_io such that repeated calls could be made. This
could result in the the driver using stale (NULLed-out, in
dev_loss_tmo) data from the rport. Correct this by addint a
simple check to ensure a valid fcport is attached.
