[SCSI] qla2xxx: Correct domain/area exclusion logic.
In an FL topology, limit port recognition to those devices
not within the same area and domain of the ISP. The
firmware will recogonize such devices during local-loop
discovery.
Some devices may respond to a PLOGI before they have
completed their fabric login or they may not be a public
device. In this case they will report:
domain == 00
area == 00
alpa == <XX>
which is valid. Exclude such devices from local loop
discovery.
