This is a bug fix based on a problem reported on the mailing list.
For very large read/write operations, ompio breaks the operation
down into multiple cycles. The problem was that
one of the variables required to maintain its values
across the different cycles did not do that, and because
of that the calculations of the memory offsets was wrong.
Fixes issue #4453
