Fixed annoying errors due to my own ZLUDA PR.

Some (in retrospect) obvious issues with ZLUDA pretending to be a CUDA device needed to be addressed from my earlier PR #224 .

Now all should be fine.

[Crystools INFO] pynvml (NVIDIA) initialized.
[Crystools INFO] GPU/s:
[Crystools WARNING] GPU 0 is not supported.
[Crystools INFO] NVIDIA Driver: 511.09.01
[Crystools WARNING] No supported GPU detected.

[edit] Had to comment out an annoying console.warning. There was probably a better solution:

    if (data.gpus === undefined || data.gpus.length === 0) {
      // console.warn('UpdateAllMonitors: no GPU data');
      return;
    }
