      ath10k: strip qos data bit always · 8bad8dcd

      NativeWifi tx mode expects QoS Data frames to be
      delivered as Data frames with QoS part (e.g. tid)
      being delievered out-of-band in fw tx command.
      
      The QoS bit wasn't stripped before submitting to
      firmware.
      
      Stripping fixes two known problems:
      
       * qca6174 IOT with some APs, e.g.
         Cisco AIR-AP 1252 (which would crash after
         ath10k association). Some ath9k APs would
         crash as well.
      
       * sniffing own tx frames via radiotap because,
         e.g. wireshark was seeing QoS bit set but
         since QoS Control was stripped in ath10k it
         would parse beginning of LLC/SNAP
      
      >From debugability point of view this removes the
      ability to distinguish QoS from non-QoS frames
      when sniffing own tx via radiotap. On the other
      hand frames can be now parsed correctly without
      special software modification.
