RRFS smoke fix

[mkavulich]

Description of Changes:

This PR fixes an issue in the current UFS code where the smoke emissions from the CFBM fire_behavior module do not persist in subsequent timesteps. Only a few instantaneous pixels of smoke can be seen in the first layer. This series of images shows smoke concentrations in the first layer at 3 h, 4 h, 5h and 6 h lead times using the current UFS weather model code:

After the fix, smoke now accumulates properly in the atmosphere over time:

Tests Conducted:

Ran the above-mentioned UFS tests with fire model enabled to show that the problem is now fixed.

UFS regression tests on Ursa were successful: only expected changes to fire behavior test.
