Xin Long 10ddceb22b ip_tunnel:multicast process cause panic due to skb->_skb_refdst NULL pointer
when ip_tunnel process multicast packets, it may check if the packet is looped
back packet though 'rt_is_output_route(skb_rtable(skb))' in ip_tunnel_rcv(),
but before that , skb->_skb_refdst has been dropped in iptunnel_pull_header(),
so which leads to a panic.
