[PLM] error mentioning the GPU driver is printed on fallback due to < min spec GPU

Progressive Lightmapper


To reproduce this, you will need a GPU that has <4GB of RAM (mine is an NVidia 1060)

Repro steps:
- download this project
- try to generate lighting using the Progressive GPU
- notice errors in the console:

Failed to find a suitable OpenCL device, falling back to CPU lightmapper.

Failed to find a suitable OpenCL device for the GPU Lightmapper, falling back to CPU lightmapper. Please install the latest graphics driver.

I checked and I do have the latest NVidia driver so the error message is not correct.

NOTE: i do also get the correct warning
OpenCL GPU device GeForce GTX 1060 3GB from NVIDIA Corporation has less than 4 GB of global memory, ignoring device for lightmapping.

Reproducible with Unity 2021.1.0a1, 2021.1.0a4 and 2020.2.0b10

The first error message is there in 2020.1, but not the second, driver-related error.
