For policy routing, packets originating from this machine itself may be
routed differently to packets passing through. We want this packet to be
routed as if it came from this machine itself. So re-compute the routing
information using ip_route_me_harder().
This patch is derived from work by Ken Brownfield
This patch (-stable version) also includes commit
b4c4ed175f ([NETFILTER]: add type parameter
to ip_route_me_harder), which is a precondition for the fix.
