[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.
