Subject: [PATCH] bridge: simplify a br_multicast_query_received() function call

The call from the IPv6 part can be simplified as the beginning of the
calling function ensures that we end up here when having a proper IPv6
source address only.

Introduced by 6565b9eeef194afbb3beec80d6dd2447f4091f8c
("bridge: multicast: add sanity check for query source addresses")
