xfrm: Fix NULL pointer dereference on policy lookup
[ Upstream commit b1e3a5607034aa0a481c6f69a6893049406665fb ]
When xfrm interfaces are used in combination with namespaces
and ESP offload, we get a dst_entry NULL pointer dereference.
This is because we don't have a dst_entry attached in the ESP
offloading case and we need to do a policy lookup before the
namespace transition.
Fix this by expicit checking of skb_dst(skb) before accessing it.
Fixes: f203b76d78092 ("xfrm: Add virtual xfrm interfaces")
