wfx_tx_confirm_cb() retrieves the station associated with a frame using the MAC address from the 802.11 header. In the other side wfx_tx() retrieves the station using sta field from the ieee80211_tx_control argument. In wfx_cqm_bssloss_sm(), wfx_tx() was called directly without valid sta field, but with a valid MAC address in 802.11 header. So there the processing of this packet was unbalanced and may produce weird bugs.
