PM / suspend: Clear wakeups before running PM callbacks

Browse Source 
PM callbacks can be used as an indicator that the system is suspending, and
as such, a wakeup may be issued outside the notifier in order to cancel an
ongoing suspend. Clearing wakeups after running the PM callbacks can thus
cause wakeups to be missed. Fix it by simply clearing wakeups prior to
running PM callbacks.
