Felix Fietkau efff395e97 ath9k: improve reliability of beacon transmission and stuck beacon handling ... ath9k calls ath9k_hw_stoptxdma every time it sends a beacon, however there is not much point in doing that if the previous beacon and mcast traffic went out properly. On AR9380, calling that function too often can result in an increase of stuck beacons due to differences in the handling of the queue enable/disable functionality. With this patch, the queue will only be explicitly stopped if the previous data frames were not sent successfully. With the beacon code being the only remaining user of ath9k_hw_stoptxdma, this function can be simplified in order to remove the now pointless attempts at waiting for transmission completion, which would never happen at this point due to the different method of tx scheduling of the beacon queue.
