  SVN rev 189091 on 2009-02-26 21:33:48Z by mav
  
  Remove direct ata_completed() call options from ata_finish(), except for the
  kernel dumping case.
  
  ata_completed() may initiate ata_reinit() on error, that may lead to drives
  attach or detach. Attach and detach are sending requests to drives and sleep
  waiting for results. But ata_finish() can be called directly from
  interrupt handler where sleeping is prohibited, so we must break this chain
  somewhere. This place seems to fit best.
