The struct page_pool_params definition has a private
definition on it:

    struct page_pool_params {
	struct_group_tagged(page_pool_params_fast, fast,
		unsigned int	order;
		unsigned int	pool_size;
		int		nid;
		struct device	*dev;
		struct napi_struct *napi;
		enum dma_data_direction dma_dir;
		unsigned int	max_len;
		unsigned int	offset;
	);
	struct_group_tagged(page_pool_params_slow, slow,
		struct net_device *netdev;
		unsigned int queue_idx;
		unsigned int	flags;
    /* private: used by test code only */
		void (*init_callback)(netmem_ref netmem, void *arg);
		void *init_arg;
	);
   };

This makes kernel-doc parser to miss the end parenthesis of
the second struct_group_tagged, causing documentation issues.

Address it by ensuring that, if are there anything at the stack,
it will be placed as the last part of the argument.
