Check and potentially fix the usage of GetProcessUtilization parameters

[metalmatze]

Hey @metalmatze, sorry for chiming in. I was checking this code to see how the nvidia API was used, and I'm wondering if the parameter expected by GetProcessUtilization is the PID.

The function is defined in without a name for the parameter,

https://github.com/NVIDIA/go-nvml/blob/62ce1e3ba862fb2f4ab5d7938bfec0a5ad0044cb/pkg/nvml/zz_generated.api.go#L918

But from

https://github.com/NVIDIA/go-nvml/blob/62ce1e3ba862fb2f4ab5d7938bfec0a5ad0044cb/pkg/nvml/device.go#L1816-L1819

it seems to be the last timestamp instead of pid.
