net: Add missing extra2 parameter for ip_default_ttl sysctl
Commit 76e6ebfb40a2455c18234dcb0f9df37533215461 ("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 e84f84f276473dcc673f360e8ff3203148bdf0e2 ("netns: place rt_genid into struct net") is applied, we'll oops in rt_cache_invalidate(). Set extra2 to init_net, to avoid that.
