mac80211: do not drop tx nulldata packets on encrypted links
commit 2463ec86 upstream. ieee80211_tx_h_select_key drops any non-mgmt packets without a key when encryption is used. This is wrong for nulldata packets that can't be encrypted and are sent out for probing clients and indicating 4-address mode.
