I don't think this change is safe since we might loose the
redirect counter and have endless redirect loops. ipip for
example calls skb_realloc_headroom, which clones the skb
when delta > 0, so it seems we really need to copy tc_verd
in skb_clone(). Generally the assumption that drivers don't
clone packets doesn't seem safe.
