NM won't clean up WoL (and WoWLAN) enabled interfaces since v1.0
(commit 1218b7e0)  back in 2014.

Instead it'll postpone doing anything with the supplicant until resume.
 So I wouldn't expect this to be a problem with NM unless there's an NM
bug, which is always possible.

More information needed (like NM version and NM debug logs), but I
think you're right that this patch isn't the right way to address the
problem.
