PM: Allow wakeup events to abort freezing of tasks
If there is a wakeup event during the freezing of tasks, suspend or
hibernation will fail anyway. Since try_to_freeze_tasks() can take
up to 20 seconds to complete or fail, aborting it as soon as a wakeup
event is detected improves the worst case wakeup latency.
Based on a patch from Arve Hjønnevåg.
