net: bridge: vlan: enable mcast snooping for existing master vlans

Browse Source 
We always create a vlan with enabled mcast snooping, so when the user
turns on per-vlan mcast contexts they'll get consistent behaviour with
the current situation, but one place wasn't updated when a bridge/master
vlan which already exists (created due to port vlans) is being added as
real bridge vlan (BRIDGE_VLAN_INFO_BRENTRY). We need to enable mcast
snooping for that vlan when that happens.
