None of this reasoning is specific to the STOP_AP event, and I'd hate us
adding it one by one...

I still think there isn't all that much reason to have it (if userspace
really needs the names so badly it could also subscribe to the rtnetlink
and keep a table of index/names!), but I could get behind a refactoring
of all these places (I count at least 10 events that include the wdev
id) to combine the four lines in the patch below into a single helper.
