wifi: mac80211: fix link activation settings order
[ Upstream commit 01605ad6c3e8608d7e147c9b75d67eb8a3d27d88 ]
In the normal MLME code we always call
ieee80211_mgd_set_link_qos_params() before
ieee80211_link_info_change_notify() and some drivers,
notably iwlwifi, rely on that as they don't do anything
(but store the data) in their conf_tx.
Fix the order here to be the same as in the normal code
paths, so this isn't broken.
