scsi: qla2xxx: Fix N2N stuck connection

commit 881eb861ca3877300570db10abbf11494e48548d upstream.

Disk failed to rediscover after chip reset error injection. The chip reset
happens at the time when a PLOGI is being sent. This causes a flag to be
left on which blocks the retry. Clear the blocking flag.
