The only thing I can remotely think of is that iwlwifi doesn't like
being called back from within the call that it did to mac80211, which
obviously happens here. But I have no idea, the code as it stands is
correct, just the interaction with iwlwifi's resume seems to be broken.

Try this patch instead:
