In commit b19fa1fa91845234961c64dbd564671aa7c0fd27, the configuration
parameter NETDEVICES_MULTIQUEUE was eliminated making multiple TX queues
the normal behavior. For p54usb, enabling multiple queues broke the driver.

A temporary hack that forces only one queue is presented here. With it, the 
driver works as before. Obviously, a proper fix is needed in the long run.
