bridge: separate querier and query timer into IGMP/IPv4 and MLD/IPv6 ones
Currently we would still potentially suffer multicast packet loss if there is just either an IGMP or an MLD querier: For the former case, we would possibly drop IPv6 multicast packets, for the latter IPv4 ones. This is because we are currently assuming that if either an IGMP or MLD querier is present that the other one is present, too. This patch makes the behaviour and fix added in "bridge: disable snooping if there is no querier" (b00589af3b04) to also work if there is either just an IGMP or an MLD querier on the link: It refines the deactivation of the snooping to be protocol specific by using separate timers for the snooped IGMP and MLD queries as well as separate timers for our internal IGMP and MLD queriers.
