block: move sched debugfs register into elvevator_register_queue
sched debugfs shares same lifetime with scheduler's kobject, and same
lock(elevator lock), so move sched debugfs register/unregister into
elevator_register_queue() and elevator_unregister_queue().
Then we needn't blk_mq_debugfs_register() for us to register sched
debugfs any more.
