bpf: also call skb_postpush_rcsum on xmit occasions
Follow-up to commit f8ffad69c9f8 ("bpf: add skb_postpush_rcsum and fix
dev_forward_skb occasions") to fix an issue for dev_queue_xmit() redirect
locations which need CHECKSUM_COMPLETE fixups on ingress.
For the same reasons as described in f8ffad69c9f8 already, we of course
also need this here, since dev_queue_xmit() on a veth device will let us
end up in the dev_forward_skb() helper again to cross namespaces.
Latter then calls into skb_postpull_rcsum() to pull out L2 header, so
that netif_rx_internal() sees CHECKSUM_COMPLETE as it is expected. That
is, CHECKSUM_COMPLETE on ingress covering L2 _payload_, not L2 headers.
Also here we have to address bpf_redirect() and bpf_clone_redirect().
Fixes: 3896d655f4d4 ("bpf: introduce bpf_clone_redirect() helper")
Fixes: 27b29f63058d ("bpf: add bpf_redirect() helper")
