ixgbe: optimize for XDP_REDIRECT in xsk path
Optimize ixgbe_run_xdp_zc() for the XDP program verdict being
XDP_REDIRECT in the xsk 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 a little under 100k extra
packets in throughput on my server when running l2fwd in xdpsock.
