Fix sporadic CUDA launch failures with Cycles viewport denoising
Sometimes the viewport buffer size is zero for a frame, which caused the
denoising task to also try to
launch CUDA kernels with a launch size of zero, which in turn failed with a
CUDA error. This patch
prevents launches from occuring in this case, similar to how it is handled in
`copy_to_display_buffer`.
