block: don't remove hctx debugfs dir from blk_mq_exit_queue
The queue's top debugfs dir is removed from blk_release_queue(), so all
hctx's debugfs dirs are removed from there. Given blk_mq_exit_queue()
is only called from blk_cleanup_queue(), it isn't necessary to remove
hctx debugfs from blk_mq_exit_queue().
So remove it from blk_mq_exit_queue().
