zeros in ocean post grib2 files on hera

[JessicaMeixner-NOAA]

What is wrong?

When running with the sea-ice PR that was just merged, so essentially develop as of today, it was noticed by @SulagnaRay-NOAA that all of the ocean grib2 files are constant values (mostly zeros). The native model output is not zeros and the ice gribs also appear to be okay.

Investigation as to what is going on and why is ongoing.

What should have happened?

We should have grib2 output files that match the native model output (and have non-zero/constant values).

What machines are impacted?

Hera

Steps to reproduce

This was discovered running a C384 test case of C384mx025_3DVarAOWCDA. However, I suspect other test cases would expose this issue as well.
