i40e: update xdp_rxq_info::frag_size for ZC enabled Rx queue

Browse source 
[ Upstream commit 0cbb08707c ]

Now that i40e driver correctly sets up frag_size in xdp_rxq_info, let us
make it work for ZC multi-buffer as well. i40e_ring::rx_buf_len for ZC
is being set via xsk_pool_get_rx_frame_size() and this needs to be
propagated up to xdp_rxq_info.
