bridge: Fix MLD queries' ethernet source address
Map the IPv6 header's destination multicast address to an ethernet
source address instead of the MLD queries multicast address.
For instance for a general MLD query (multicast address in the MLD query
set to ::), this would wrongly be mapped to 33:33:00:00:00:00, although
an MLD queries destination MAC should always be 33:33:00:00:00:01 which
matches the IPv6 header's multicast destination ff02::1.
