power: wakelock: don't set check_done flag if aborting

If there is a wakelock held the wakelock driver rejects the suspend
by returning EAGAIN(-11). In this case since the suspend is rejected
in suspend_noirq callback, the resume_noirq callback is not called on
the wakelock driver, leading to the check_done flag not being cleared
and causing a BUG for the next wakelock request.

Don't set the check_done flag if suspend_noirq aborts suspend.
