nvvs (DCGM validation suite) survives when dcgmi is killed mid-run,
leaving the GPU occupied. The next dcgmi diag invocation then fails
with "affected resource is in use".
Two-part fix:
- Add nvvs and dcgmi to KillTestWorkers patterns so they are cleaned
up by the global cancel handler
- Call KillTestWorkers at the start of RunNvidiaTargetedStressValidatePack
to clear any stale processes before dcgmi diag runs
