Commit 76e6ebfb ("netns: add namespace
parameter to rt_cache_flush") acceses the extra2 parameter of the
ip_default_ttl ctl_table, but it is never set to a meaningful
value. When e84f84f2 ("netns: place
rt_genid into struct net") is applied, we'll oops in
rt_cache_invalidate(). Set extra2 to init_net, to avoid that.
