xfrm: force a dst reference in __xfrm_route_forward()
Packets going through __xfrm_route_forward() have a not refcounted dst
entry, since we enabled a noref forwarding path.
xfrm_lookup() might incorrectly release this dst entry.
It's a bit late to make invasive changes in xfrm_lookup(), so lets force
a refcount in this path.
