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().
