In the future, it is possible that we will want a fallback for other multicast groups as well. Would it make sense to make the fallback group an argument to nl_lookup_genl_mcgroup(), with zero to disable fallback? (Of course nl_lookup_genl_mcgroup() would still log a message that the fallback was in use.) Then it will simplify later work, if there is any.
