1. If route was host route, check that
cached destination is current.
If it is network route, we still may
check its validity using saved pointer
to the last used address: daddr_cache.
We do not want to save whole address now,
(because main consumer of this service
is tcp, which has not this problem),
so that the last trick works only on connected
sockets.
2. oif also should be the same.
