[PATCH] block/mq-deadline: Fix compilation warning.

[Imran Khan <imran.f.khan@oracle.com>]

dd_queued is only being used by show function corresponding to queued
attribute. So compilation without BLK_DEBUG_FS gives unused-function
warning for dd_queued.
Move dd_queued under BLK_DEBUG_FS to fix compilation issue.

Fixes: 7b05bf771084 ("Revert "block/mq-deadline: Prioritize high-priority requests"")
