ACPI: don't check power state after _ON/_OFF
We used to evaluate _STA to check the power state of a device after running _ON or _OFF. But as far as I can tell, there's no benefit to evaluating _STA, and sometimes we trip over bugs when BIOSes don't implement _STA correctly. Yakui says Windows XP doesn't evaluate _STA during power transition. So let's skip it in Linux, too. It's conceivable that we'll need to check _STA in the future for some reason, but until we do, I don't see a reason to clutter this code path.
