History
Poul-Henning Kamp 37f5e4a6c2 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.
