rt_genid_bump_all() consists of ipv4 and ipv6 part.
ipv4 part is incrementing of net::ipv4::rt_genid,
and I see many places, where it's read without rtnl_lock().
ipv6 part calls __fib6_clean_all(), and it's also
called without rtnl_lock() in other places.
So, rtnl_lock() here was used to iterate net_namespace_list only,
and we can remove it.
