David Ahern 5bb115fb7d ipv6: Fix PMTU updates for UDP/raw sockets in presence of VRF 
[ Upstream commit 7ddacfa564 ]

Preethi reported that PMTU discovery for UDP/raw applications is not
working in the presence of VRF when the socket is not bound to a device.
The problem is that ip6_sk_update_pmtu does not consider the L3 domain
of the skb device if the socket is not bound. Update the function to
set oif to the L3 master device if relevant.

Fixes: ca254490c8 ("net: Add VRF support to IPv6 stack")
