Edgar Gabriel c0f8ce0fff common/ompio: fix a floating point division problem
This commit fixes  a problem reported on the mailing list with
individual writes larger than 512 MB.

The culprit is a floating point division of two large, close values.
Changing the datatypes from float to double (which is what is being
used in the fcoll components) fixes the problem.

See issue #6285 and

 https://forum.hdfgroup.org/t/cannot-write-more-than-512-mb-in-1d/5118

Thanks for Axel Huebl and René Widera for reporting the issue.
