Seokmann Ju 99363ef81c [SCSI] qla2xxx: Correct issue where vport-state was not updated during an ISP_ABORT_NEEDED requst. 
While running IO simultaneously through physical port and virtual
port, if user changes Data Rate (from scli utility), IO through
virtual port fails.  It failed because the vport had not received
the ISP_ABORT_NEEDED notification.
