Similar to how it's done in the ice driver since 'eb087cd82864 ("ice:
propagate xdp_ring onto rx_ring")', read the XDP program once per NAPI
instead of once per descriptor cleaned. I measured an improvement in
throughput of 2% for the AF_XDP xdpsock l2fwd benchmark for zero copy mode
and 1% for copy mode.
