wifi: b43: Stop/wake correct queue in PIO Tx path 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/wake queue 0 when QoS
is disabled to prevent trying to stop/wake a non-existent queue and failing
to stop/wake the actual queue instantiated.

Fixes: 5100d5ac81 ("b43: Add PIO support for PCMCIA devices")
