Similar to commit c29390c6dfee ("xps: must clear sender_cpu before forwarding")
the skb->sender_cpu needs to be cleared before xmit.
Fixes: 3896d655f4d4 ("bpf: introduce bpf_clone_redirect() helper")
Signed-off-by: Alexei Starovoitov <a...@plumgrid.com>

That is similar to pending patches for xps:
http://patchwork.ozlabs.org/patch/526952/
and for act_mirred:
http://patchwork.ozlabs.org/patch/527066/
though Fixes tag is different, since bpf_clone_redirect() came in
after commit 2bd82484bb4c ("xps: fix xps for stacked devices")
