ipv4: rt_cache_valid must check expired routes
commit d2d68ba9fe8 (ipv4: Cache input routes in fib_info nexthops.) introduced rt_cache_valid() helper. It unfortunately doesn't check if route is expired before caching it. I noticed sk_setup_caps() was constantly called on a tcp workload. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
