This change ensures that the new multicast active state variable is immediately unset if our internal IGMP/MLD querier was elected and now disabled.
If no IGMP/MLD querier exists on the link then we can't reliably receive IGMP/MLD reports and in turn can't ensure the completeness of our MDB anymore either. No functional change for the fast/data path yet. This is the last necessary check before using the new multicast active state variable in the fast/data path, too.
