Subject: [PATCH net-next v4 2/2] tipc: remove invalid ip_rt_put

udp_tunnel_xmit_skb() will free the skb and release the rt->dst
reference in the error case. There is no need (and it would actully
trigger a warning) when we did.
This problem was not visible before, as udp_tunnel_xmit_skb() would
never return a value < 0
