wifi: b43: Stop correct queue in DMA worker when QoS is disabled
When QoS is disabled, the queue priority value will not map to the correct
ieee80211 queue since there is only one queue. Stop queue 0 when QoS is
disabled to prevent trying to stop a non-existent queue and failing to stop
the actual queue instantiated.
Fixes: bad691946966 ("b43: avoid packet losses in the dma worker code.")
