[SCSI] libfc: discovery retry should clear pending first.
Currently fc_disc_timeout() restarts discovery only if it is not pending.
When the timer is scheduled, the discovery is left pending, so the
timeout never restarts it.
Fix by not checking for pending in the timeout handler.
If discovery is stopped and restarted in the meantime, the timeout will
be canceled.
Also, when a new discovery is started, the retry count wasn't cleared.
