[GPU PLM] Different results are generated when Progressive Updates is on or off while "Progressive GPU" Lightmapper is selected

Progressive Lightmapper

-

How to reproduce:
1. Open the user's attached "ProgressiveUpdates" project
2. Open the "home_night_2" Scene
3. In the Scene view focus on the "Point light(1)" GameObject and the corner it lights up
4. Open the Lighting settings (Window->Rendering->Lighting)
5. Clear Baked Data (drop-down menu on "Generate Lighting"->Clear Baked Data)
6. Generate Lighting
7. Observe the corner
8. Check the "Progressive Updates" option (uncheck if it was checked)
9. Repeat steps 5-7

Expected results: Both times the wall lit by the light looks the same
Actual results: There are white spots on the walls when "Progressive Updates" is off and none when it's on

Reproducible with: 2021.2.0a9, 2021.2.0b7, 2022.1.0a5
Not reproducible with: 2019.4.29f1, 2020.3.16f1, 2021.1.17f1, 2021.2.0a8

Note:
- The issue is not reproducible if Lightmapper is set to "Progressive CPU"
