blk-mq: Only register debugfs attributes for blk-mq queues

The code in blk-mq-debugfs.c assumes that it is working on a blk-mq
queue and is not intended to work on a blk-sq queue. Hence only
register blk-mq debugfs attributes for blk-mq queues.

Fixes: commit 9c1051aacde8 ("blk-mq: untangle debugfs and sysfs")
