Fixes an issue where Blender would crash if the OptiX denoiser was selected, but an unsupported GPU device (E.g. Intel GPU) was selected in preferences. This crash would occur because Cycles uses the device in preferences to setup the denoiser, and there was no check stopping an unsupported GPU from being used to try and setup and run the denoiser.
