dm: update dm_process_bio() to split bio if in ->make_request_fn() Must call blk_queue_split() otherwise queue_limits for abnormal requests (e.g. discard, writesame, etc) won't be imposed. In addition, add dm_queue_split() to simplify DM specific splitting that is needed for targets that impose ti->max_io_len. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
