PM / Wakeup: Replace pm_check_wakeup_events() with pm_wakeup_pending()

Browse Source 
To avoid confusion with the meaning and return value of
pm_check_wakeup_events() replace it with pm_wakeup_pending() that
will work the other way around (ie. return true when system-wide
power transition should be aborted).
