batman-adv: Avoid old nodes disabling multicast optimizations completely
Instead of disabling multicast optimizations mesh-wide once a node with no multicast optimizations capabilities joins the mesh, do the following: Just insert such nodes into the WANT_ALL_IPV4/IPV6 lists. This is sufficient to avoid multicast packet loss to such unsupportive nodes.
