[PATCH] ipv6: enable net.ipv6.route sysctls in network namespace

[Alexander Kuznetsov <wwfq@yandex-team.ru>]

We want to increase route cache size in network namespace
created with user namespace. Currently ipv6 route settings
are disabled for non-initial network namespaces.
Since routes are per network namespace it is safe
to enable these sysctls.
