  SVN rev 219135 on 2011-03-01 14:43:37Z by jhb
  
  Similar to 189574, properly handle subclasses of bus drivers when deleting
  a driver during kldunload.  Specifically, recursively walk the tree of
  subclasses of a given driver attachment's bus device class detaching all
  instances of that driver for each class and its subclasses.
