  Log:
  Fix a problem and slightly improve the ENOMEM handling:
  
  Give up the entire bio as soon as we detect a problem.
  
  When we detect a problem, give up the bio by contributing the
  remainder with ENOMEM, rather than kicking the bio back right
  away.
  
  If we failed on a non-first iteration we previously could end up
  modifying fields in the bio after we delivered it.  This could
  account for memory corruption (none directly reported) on machines
  with GBDE.
