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

commit 2e7e9c308956ada8c52f1da8f00f167f74f39286 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.
