This will fix the immediate problem, but not in general. What if we're
joined to an IBSS while suspending? A similar thing could happen. Or
operating as an AP? Or joined to a mesh? etc.
I think it'd be better to implement this as explicit disconnect, leave,
teardown, whatever ... in cfg80211 rather than mac80211, although then
of course mac80211 could have a bunch of cleanups, e.g. the various
_quiesce functions could be reduced then I think.
