pf: Improve route-to handling of pfsync'd states
When a state if pfsync’d to a different host it doesn’t get all of the expected pointers, including the pointer to the struct pfi_kif / struct ifnet rt_kif pointer. (I.e. the interface to route out on). That in turn means that pf_route() ends up dropping the packet. Use the rule's struct pfi_kif pointer so we can still route out of the expected interface. MFC after: 2 weeks Sponsored by: Orange Business Services (cherry picked from commit 81ef217ad428c29be669aac2166d194db31817a7)
