[PATCH] ip route: timeout for routes has to be set in seconds

[Andrey Vagin <avagin@openvz.org>]

From: Andrew Vagin <avagin@virtuozzo.com>

Currently a timeout is multiplied by HZ in user-space and
then it multiplied by HZ in kernel-space.

$ ./ip/ip r add 2002::0/64 dev veth1 expires 10
$ ./ip/ip -6 r
2002::/64 dev veth1  metric 1024 linkdown  expires 996sec pref medium
