  SVN rev 214666 on 2010-11-02 09:05:40Z by mav
  
  MFC r214102:
  Workaround strange situation when EDMA_RESQIP register returns zero instead
  of proper value. It caused bunch of "EMPTY CRPB" messages and potentially
  may cause premature requests completion, which could cause data corruption.
  For most cases it seems enough to just reread register to get proper value.
  To protect against worse cases - erase processed queue entries with
  impossible values and ignore them if problem still happen.
