    bridge: fix lookup for untagged packets in bridge_transmit()
    
    b0e38a1373 improved if_bridge's ability to cope with different VLANs,
    but it failed to update bridge_transmit() to cope with the new rule that
    untagged packets are treated as having VLAN ID 0 (rather than 1, as used
    to be the case).
    
    Fix that oversight.
