[PATCH 1/2] smartpqi: workaround fw bug for oq deletion

[Don Brace <don.brace@xxxxxxxxxxxxx>]

From: Kevin Barnett <kevin.barnett@xxxxxxxxxxxxx>

- skip deleting PQI operational queues when there is
  an error creating a new queue group. It's not really necessary to
  delete the queues anyway because they get deleted during the PQI
  reset that is part of the error recovery path.
