[SCSI] qla2xxx: Correct rport/fcport visibility-state handling during loop-resync.
There were several issues here, one, during RSCN handling if a
follow-on RSCN occurred (within interrupt context) the DPC thread
could inadvertantly leave the fcport in a stale lost state.
Secondly, scheduled rport removal is handled exclusively by the
'parent' DPC thread, so wake up the proper thread. Finally,
process vport loop-resync's only when the vport has in an
"active" state (ID acquired).
