The behavior appears to have been changed in:

mac80211: don't call mgd_prepare_tx when associated
I am not sure how it can be guaranteed that the driver is
on the right context when trying to send a mgmt frame.
ath9k uses mgd_prepare_tx() to switch to the required context,
so I think this call is necessary even if we are associated.
