vrf: Increment Icmp6InMsgs on the original netdev
[ Upstream commit e1ae5c2ea4783b1fd87be250f9fcc9d9e1a6ba3f ]
Get the ingress interface and increment ICMP counters based on that
instead of skb->dev when the the dev is a VRF device.
This is a follow up on the following message:
https://www.spinics.net/lists/netdev/msg560268.html
v2: Avoid changing skb->dev since it has unintended effect for local
delivery (David Ahern).
