ath9k: fix btcoex duty cycle
* Reset duty cycle before updating btcoex scheme. Otherwise duty cycle reaches max limit and never be reduced again * Adjust duty cycle with proper BDR profile value Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
