  SVN rev 190669 on 2009-04-03 10:38:24Z by mav
  
  MFC rev. 188464.
  
  Check for device_set_devclass() errors and skip driver probe/attach if any.
  Attach called without devclass set crashes the system.
  
  On attach/resume some ATA drivers sometimes trying to create duplicate adX
  device. It is surely their own problem, but it is not a reason to crash here.
