Moved wakelock logs to the notifier thread

This is to improve the wakelock acquire and release latency. It was
noted that over 10% of the time spent in acquiring a wakelock was while
logging its state. This moves that aspect of logging to the notfier thread,
essentially making the power thread run faster.
