[GPU PLM] Texels are marked as invalid when hitting a backface even with 0 bounces

Global Illumination

-

Steps to reproduce:

1. Open the attached project (GPUPLMInvalidTexelsTest01)
2. Navigate to Lighting Settings and make sure that Progressive CPU is set as the lightmapping backend
3. Bake the lighting
4. Now switch lightmapping backend to Progressive GPU and rebake
5. Notice the artifacts caused by invalid texels

Notes:

- Reproduces only with GPU PLM when Bounces count is set to 0
- If Bounces count is set to > 0 the issue reproduces on both backends - that is expected
