From: Johannes Berg <johannes.berg@xxxxxxxxx>
If resume fails, we should shut down all interfaces as the
hardware is probably dead. This was/is already done now in
mac80211, but we need to change that due to locking issues,
so move it here and do it without the wiphy lock held.
Fixes: 2fe8ef106238 ("cfg80211: change netdev registration/unregistration semantics")
