qla2xxx: Remove restriction on starting remote device discovery on port update.
Limiting which port update events will allow the driver to kick off a
name server scan has been problematic in some corner cases so remove the
restriction and restore the previous semantic. Also move the link
up/down informational messages to the LOOP_UP and LOOP_DOWN events.
