[SCSI] libfc: fix: cancel rport retry timer
The timer for rport retries wasn't getting canceled, and would occasionally go off after the module was unloaded. Add logic to cancel the timer in fc_rport_work(). Since we cancel the timer before deleting the rdata, it is no longer necessary to do a get_device() for the pending timer.
