Subject: [PATCH] block/mq-deadline: Move dd_queued() to fix defined but not used warning

    block/mq-deadline.c:274:12: warning: ‘dd_queued’ defined but not used [-Wunused-function]
      274 | static u32 dd_queued(struct deadline_data *dd, enum dd_prio prio)
	  |            ^~~~~~~~~

Fix this by moving dd_queued() just before the sole function that calls
it.
