From: Joe Eykholt <jeykholt@xxxxxxxxx>
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.
