bridge: modify bridge and port to have often accessed fields in one cache line
Move around net_bridge so the vlan fields are in the beginning since they're checked on every packet even if vlan filtering is disabled. For the port move flags & vlan group to the beginning, so they're in the same cache line with the port's state (both flags and state are checked on each packet).
