3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <nbd@xxxxxxxx>
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.
Fixes: e548c49e6dc6b ("mac80211: add key flag for management keys")
