mac80211: add atomic uploaded keys iterator
add ieee80211_iter_keys_rcu() to iterate over uploaded
keys in atomic context (when rcu is locked)
The station removal code removes the keys only after
calling synchronize_net(), so it's not safe to iterate
the keys at this point (and postponing the actual key
deletion with call_rcu() might result in some
badly-ordered ops calls).
Add a flag to indicate a station is being removed,
and skip the configured keys if it's set.
