  Modified files:
    sys/net/bridge       bridgestp.c if_bridge.c if_bridgevar.h 
  Log:
  - Check cached ifnet.if_bridge again in bridge_{input,output}()
  - Pass cached ifnet.if_bridge to bstp_input()
  - Pass the located bif to bstp_input(), so we won't need to locate bif again
  
  These changes make it possible to use following sequence
      ifp->if_bridge = NULL;
      netmsg_service_sync();
  to protect ifnet.if_bridge
