ath5k: Use new function to stop beacon queue
* Since we only use ath5k_hw_stop_tx_dma to stop the beacon
queue, introduce a new function ath5k_hw_stop_beacon_queue so
that we can use that instead and have better control. In the future
we can add more beacon queue specific stuff there (maybe tweak
beacon timers or something), for now just call ath5k_hw_stop_tx_dma.
* Also since we don't call ath5k_hw_stop_rx/tx_dma from outside
dma.c, make them static.
