scsi: qla2xxx: Fix race between switch cmd completion and timeout
Fix race condition between switch cmd completion and timeout timer. Timer
has popped triggers command free. On IOCB completion, stale sp point was
reused. Instead, an abort will be sent to FW to nudge the command out of FW
where the normal completion will take place.
