The multi-bio code is responsible for duplicating blocks in raid1 and
single spindle duplication. It has counters to make sure all of
the locations for a given extent are properly written before io completion
is returned to the higher layers.
But, it didn't always complete the same bio it was given, sometimes a
clone was completed instead. This lead to problems with the async
work queues because they saved a pointer to the bio in a struct off
bi_private.
The fix is to remember the original bio and only complete that one.
