ip_tunnel:multicast process cause panic due to skb->_skb_refdst NULL pointer
[ Upstream commit 10ddceb22bab11dab10ba645c7df2e4a8e7a5db5 ]
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.
