block: always assign default lock to queues
Move the assignment of a default lock below blk_init_queue() to blk_queue_make_request(), so we also get to set the default lock for ->make_request_fn() based drivers. This is important since the queue flag locking requires a lock to be in place. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
