cciss: Set the performant mode bit in the scsi half of the driver
In a couple of places, the performant mode bit wasn't being set in
the scsi half of the driver, causing commands to seem to hang. Use
enqueue_cmd_and_start_io() where appropriate. This fixes a bug that
echo engage scsi > /proc/driver/cciss/cciss0
would hang.
