ip6_tunnel: fix possible use-after-free on xmit
[ Upstream commit 01f5bffad555f8e22a61f4b1261fe09cf1b96994 ]
ip4ip6/ip6ip6 tunnels run iptunnel_handle_offloads on xmit which
can cause a possible use-after-free accessing iph/ipv6h pointer
since the packet will be 'uncloned' running pskb_expand_head if
it is a cloned gso skb.
