[035/289] ath9k_htc: Avoid setting QoS control for non-QoS frames

[Greg KH]

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Rajkumar Manoharan <rmanoharan@xxxxxxxxxxx>

commit 3bf30b56c4f0a1c4fae34050b7db4527c92891e8 upstream.

Setting tid information in the TX header is required only for QoS
frames. Not handling this case causes severe data loss with some APs.
