[GPU PLM] Crash due to out of bounds access violation in PowerSampling after enabling auto mode at the end of bake on AMD GPU

Progressive Lightmapper


Tested locally using Windows10 and a Threadripper 3990 ES + RX6800XT GPU using the repro project from the bug:

Steps to repro:
1. Open the attached project and 'ProgressiveLightmappingExample' scene
2. In the Preferences window (Edit > Preferences) go to the GICache tab and click the 'Clean Cache" button;
3. In the Lighting window (Window > Rendering > Lighting) click Generate Lighting button;
4. At the end of GI baking (observe the progress bar for spotting it) enable Auto Generate checkbox in the Lighting window.

Expected result:
Editor finishes an auto-bake without crashes.

Actual result:
Editor crashes.
