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.
