block/mq-deadline: Move dd_queued() to fix defined but not used warning
If CONFIG_BLK_DEBUG_FS=n:
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.
