tray: run nvidia-smi only once the GPU stays awake - #16

Conversation
In Optimus mode other programs wake the GPU for a fraction of a second. The tray's 5 s poll could catch one of those wakes and start nvidia-smi just as the GPU went back to D3, waking it again. Wait for two awake polls in a row and check once more before starting the process. An unreadable power state still allows the sample, as before.
