xsk: add missing virtual address conversion for page

In commit 7ead4405e06f ("xsk: convert xdp_copy_frags_from_zc() to use
page_pool_dev_alloc()"), when converting from netmem to page, I missed a
call to page_address() around skb_frag_page(frag) to get the virtual
address of the page. This commit uses skb_frag_address() helper to fix
the issue.
