net: Preserve netfilter attributes in skb_gso_segment using __copy_skb_header
skb_gso_segment didn't preserve some attributes in the original skb
such as the netfilter fields. This was harmless until they were used
which is the case for packets going through lo.
This patch makes it call __copy_skb_header which also picks up some
other missing attributes.
