PM / Wakeup: Don't update events_check_enabled in pm_get_wakeup_count()
Since pm_save_wakeup_count() has just been changed to clear events_check_enabled unconditionally before checking if there are any new wakeup events registered since the last read from /sys/power/wakeup_count, the detection of wakeup events during suspend may be disabled, after it's been enabled, by writing a "wrong" value back to /sys/power/wakeup_count. For this reason, it is not necessary to update events_check_enabled in pm_get_wakeup_count() any more. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
