net: icmp_route_lookup should use rt dev to determine L3 domain
icmp_send is called in response to some event. The skb may not have the device set (skb->dev is NULL), but it is expected to have an rt. Update icmp_route_lookup to use the rt on the skb to determine L3 domain. Fixes: 613d09b30f8b ("net: Use VRF device index for lookups on TX") Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
