  Modified files:
    sys/bus/cam/scsi     scsi_da.c 
  Log:
  dev_dopen() can be called multiple times with only one dev_dclose() when
  D_TRACKCLOSE is not specified.  Make sure multiple opens only reference
  the CAM peripheral once and complain if dev_dclose() is called more then
  once.
  
  This also prevents bugs in higher layers from propogating to lower ones.
