mac80211: make key locking clearer
The code in ieee80211_del_key() doesn't acquire the key_mtx properly when it dereferences the keys. It turns out that isn't actually necessary since the key_mtx itself seems to be redundant since all key manipulations are done under the RTNL, but as long as we have the key_mtx we should use it the right way too.
