page_pool: make page_pool_put_page_bulk() handle array of netmems
Currently, page_pool_put_page_bulk() indeed takes an array of pointers
to the data, not pages, despite the name. As one side effect, when
you're freeing frags from &skb_shared_info, xdp_return_frame_bulk()
converts page pointers to virtual addresses and then
page_pool_put_page_bulk() converts them back. Moreover, data pointers
assume every frag is placed in the host memory, making this function
non-universal.
Make page_pool_put_page_bulk() handle array of netmems. Pass frag
netmems directly and use virt_to_netmem() when freeing xdpf->data,
so that the PP core will then get the compound netmem and take care
of the rest.
