[SCSI] qla2xxx: Revert "qla2xxx: Use proper HA during asynchronous event handling."

This reverts commit bd2a1846b2313e32d0270151a31a6b8335384a20.
The original (prior to the reverted commit) code was correct.
Additionally, the vp_idx should be checked during MBA_PORT_UPDATE
in order for proper handling to take place for a given vport.
