Calculate the halt-polling "stop" time using "start" instead of redoing ktime_get(). In practice, the numbers involved are in the noise (e.g., in the happy case where hardware correctly predicts do_halt_poll and there are no interrupts, "start" is probably only a few cycles old) and either approach is perfectly ok. But it's more precise to count any extra latency toward the halt-polling time.
