ath9k: fix the .flush driver op implementation
This patch simplifies the flush op and reuses ath_drain_all_txq for flushing out pending frames if necessary. It also uses a global timeout of 200ms instead of the per-queue 60ms timeout. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
