NVML 11.8 API bugs

[BlueGoliath]

Hi,

The new 11.8 functions to change VF offset for GPU/Memory clock are bugged in 520 in different ways.

On my GTX 1080 the graphics clock function returns "Not Found":

and the min value returned by nvmlDeviceGetMemClkMinMaxVfOffset isn't correct. It should be -2000 for my card but instead, it returns 8587934. It works correctly otherwise although I wish it was like Windows.

Forgot to mention that I'm just setting the min memory clock to 0 for the purpose of getting it to work for now.
