4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <nbd@nbd.name>
commit 211710ca74adf790b46ab3867fcce8047b573cd1 upstream.
key->sta is only valid after ieee80211_key_link, which is called later in this function. Because of that, the IEEE80211_KEY_FLAG_RX_MGMT is never set when management frame protection is enabled.
