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.
