net/mld: There is an issue with the general query timer design. There should be a single instance, not a per-group instance of the timer (ditto for the v1 compatibility timer). Fall back for now and use the per-group MAX query.

                Instead, the design currently uses a Multicast Address Specific
                Query with one timer per group and ignores groups that we are
                not members of.
