ath10k: strip qos data bit always
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.
