1) This should be submitted against 'net' since it's clearly
   a real bug.

2) This needs to be fixed differently.  We should always
   kmemdup() and create fresh copies of these objects, even
   for init_net.  So 'dflt' and 'all' will start as "NULL"
   and always we will try to kmemdup(&ipv6_defconf, ...) and
   kmemdup(&ipv6_devconf_dflt, ...);
