[PLM] Lightmap baking is stuck with 'OpenRL error 501 in function rlViewport: RL_INVALID_VALUE' when baking

Progressive Lightmapper


Steps to repro:

1. Create a scene with LODs where lower LODs are marked static to participate in the bake.
2. In the Lighting window click Generate Lighting to bake Lighting.

Expected result:
Lighting is baked successfully.

Actual result:
Baking stalls on 'Baking...' stage and no baked lightmaps are being added.

- Reproducible in the custom build based on Unity 2018.2.0f2;
- The bug blocks the workflow of the Demo team.
- Could not retest in 2018.3 and 2019.1 as the repro project only works in 2018.2;
- The bug is also partially reproducible in FPSample project, but with different symptoms (OpenRL errors constantly fired in the console).

    Seeing the same phenomenon in 2018.3.10f1.
    Scene baked fine in 2018.2.19f1, but now it hangs at about 50%.
