ip_tunnel: Do not use stale inner_iph pointer. While sending packet skb_cow_head() can change skb header which invalidates inner_iph pointer to skb header. Following patch avoid using it. Found by code inspection. This bug was introduced by commit 0e6fbc5b6c6218 (ip_tunnels: extend iptunnel_xmit()).
