block/io: bdrv_wait_serialising_requests_locked: drop extra bs arg
bs is linked in req, so no needs to pass it separately. Most of tracked-requests API doesn't have bs argument. Actually, after this patch only tracked_request_begin has it, but it's for purpose. While being here, also add a comment about what "_locked" is.
