Now that ice driver correctly sets up frag_size in xdp_rxq_info, let us make it work for ZC multi-buffer as well. ice_rx_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. Use a bigger hammer and instead of unregistering only xdp_rxq_info's memory model, unregister it altogether and register it again and have xdp_rxq_info with correct frag_size value.
