[GPU PLM] Indirect bounce color is wrong with multi-material setups

Global Illumination


Steps to reproduce:

1. Download CornellBox scene (link in the description)
2. Make sure that GPU Lightmapper is selected as the lightmapping backed
3. Bake the lighting
4. Notice strange indirect bounce, especially evident where the ceiling and the green wall intersect


- Reproduces only on GPU PLM; CPU PLM does not suffer from this issue
- Reproduces with both directional and non-directional lightmaps
