aacraid: Remove code to needlessly complete fib
Currently driver completes double completed or spurious interrupted fibs.
This is not necessary and causes the SCSI mid layer to issue aborts and
resets, since completing a fib prematurely might trigger a race condition
resulting in the driver not calling the scsi_done callback.
Fixed by removing the call to fib complete.
