Bug fix for QPFFFG and QPFARI encoding in RRFS

[EricJames-NOAA]

prob_num and tot_num_prob were not set in grib2_module.f, resulting in seemingly random values showing up for the new GRIB2 records QPFARI and QPFFFG, as noted by Hui-Ya Chuang:

This small change fixes the issue, and should lead to bitwise identical results.

The change was tested for the RRFS_NA_3km system on Hera.

Wen won't be back for another week or two from China. She gave me directions to merge UPP codes and Fernando will help me.
I will be gone for 3 weeks after this weekend so let me know soon.

@HuiyaChuang-NOAA thanks for the update. I am working on one additional bug fix which I intend to combine with this PR. I hope to have the code ready to go tomorrow. Once that is finished, the code should be finalized for RRFS.

Ok, let me know. I will see what I can do. If I can't get to it, I will email Wen with you copied . She is hoping to be back to work the week of June 10

Looks good from my perspective.

@HuiyaChuang-NOAA @MatthewPyle-NOAA the PR is ready. The only remaining issue is that accumulated fields in the top-of-the-hour 15-min output appear with units of hours instead of minutes, and I can't figure out why that's the case. But the time labels are all correct now.

Sorry it is so late. If you can't get it merged now, I will spend some more time trying to figure out the time unit labeling issue.

@EricJames-NOAA I assume all of these bug fixes are intended for RRFS v1 implementation, right? If so, please change the merging branch from 'develop' to 'release/rrfs_v1'. Also, another UPP issue is needed for bug fixes except QPFFG and QPFARI encoding.
