Fix GDAS group b warm restart archiving

[DavidHuber-NOAA]

Description

This fixes the GDAS-cycle warm restart archiving for group b (previous cycle) by adding assim_freq to the current cycle when checking the number of days since SDATE. This is a companion PR to #4502, which fixes the same issue in the dev/gfs.v17 branch.

Resolves #4501 for develop

I have finished testing this case. The resulting archives were identical to those reported in #4502 (here). Here are the restart listings for cycles 2021122218 and 2021122300:

Launching CI on C6. Once complete, I will check the restarts for the C96C48mx500_S2SW_cyc_gfs case.

Verified that a full restart set was written for cycles 2021122018 (restart group b) and 2021122100 (restart group a) for the C96C48mx500_S2SW_cyc_gfs test case on C6:
