Optimize run_xdp_zc() for the XDP program verdict being XDP_REDIRECT in the zsk zero-copy path. This path is only used when having AF_XDP zero-copy on and in that case most packets will be directed to user space. This provides around 100k extra packets in throughput on my server when running l2fwd in xdpsock.
