[SCSI] qla2xxx: Properly re-register FC4/FDMI after physical and logical link disruptions. 

Original code would not register FC4 nor FDMI information after a
logical tear-down of an VFC link.  Code now triggers registration
date during processing of a 'Report ID Acquisition IOCB', which
is submitted after a FLOGI or FDISC completes.
