net: bridge: mcast: fix br_multicast_ctx_vlan_global_disabled helper
We need to first check if the context is a vlan one, then we need to check the global bridge multicast vlan snooping flag, and finally the vlan's multicast flag, otherwise we will unnecessarily enable vlan mcast processing (e.g. querier timers).
