Subject: scsi: qla2xxx: Fix losing FCP-2 targets on long port disable with I/Os

From: Arun Easi <aeasi@xxxxxxxxxxx>

commit 2416ccd3815ba1613e10a6da0a24ef21acfe5633 upstream.

FCP-2 devices were not coming back online once they were lost, login
retries exhausted, and then came back up.  Fix this by accepting RSCN when
the device is not online.
