bridge: fix br_multicast_query_expired() bug
br_multicast_query_expired() querier argument is a pointer to
a struct bridge_mcast_querier :
struct bridge_mcast_querier {
struct br_ip addr;
struct net_bridge_port __rcu *port;
};
Intent of the code was to clear port field, not the pointer to querier.
Fixes: 2cd4143192e8 ("bridge: memorize and export selected IGMP/MLD querier port")
