This is a fix based on a bugreport on github/mailing list from CGNS.
The core of the problem was that different processes entered different branches of
our aggregator selection logic, due to the fact that in some cases processes had
a matching file_view size and contiguous chunk size (thus assuming 1-D distribution),
and some processes did not (thus assuming 2-D distribution). The fix is to calculate
the avg. file view size across all processes and use this value, thus ensuring that
all processes enter the same branch.
Fixes issue #7809
