perf tests sched: Avoid error in cleanup on loaded machines



The stop_noploops function will kill the noploop processes that are
running for 10 seconds.

On a loaded machine they may have already terminated meaning the kill
will return an error of no such process.

This doesn't matter and so ignore the error to avoid the test
terminating in the cleanup.
