ath9k: fix rate handling/reporting
This patch fixes some issues introduced in the rate control API rework. When not running aggregation, copy bf->rates into info->control.rates before applying the rate control status to it. In ath_lookup_rate, the rates need to be pulled from bf->rates, not the tx info. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
