i40e, xsk: Migrate to new MEM_TYPE_XSK_BUFF_POOL
Remove MEM_TYPE_ZERO_COPY in favor of the new MEM_TYPE_XSK_BUFF_POOL
APIs. The AF_XDP zero-copy rx_bi ring is now simply a struct xdp_buff
pointer.
v4->v5: Fixed "warning: Excess function parameter 'bi' description in
'i40e_construct_skb_zc'". (Jakub)
