Hmm, I'm not sure I like this direct, unconditional fiddling with a
VAP's state in the stop function, have you made sure that there are no
side effects? eg. in case no VAP exists? I remember running into issue
while doing that on iwn(4) and it helped to not have any knowledge
about ic or vap in either init() or stop(). Well, I've settled for
ieee80211_stop() and ieee80211_start() in suspend/resume, which seems
to work.
