ipv6: udp: Use ip6_sk_redirect() for tunnel sockets

Browse source

After commit cd51b74bdd ("ipv6: Fix redirect exception creation for
UDP/RAW sockets") the two redirect calls are now equivalent and there is
no need to specifically call ip6_redirect() for tunnel sockets. Simplify
and call ip6_sk_redirect() for both tunnel sockets and regular sockets.

Note that for ICMPv6 Redirect Message packets the VRF driver does not
reset skb->dev to the VRF device, so skb->dev->ifindex is equivalent to
inet6_iif(skb), even when the packet was received from a VRF port.
