Subject: [PATCH 2/5] nbd: use __blk_mq_complete_request in timeout path

To regain the capability to prevent normal completion path from
entering a timeout request, blk_mq_mark_rq_complete is introduced
in blk_mq_complete_request. Have to use __blk_mq_complete_request
in timeout path to complete a timeout request.
