b43legacy: Avoid packet losses in the dma worker code

Browse source 
This patch addresses a bug in the dma worker code that keeps draining
packets even when the hardware queues are full. In such cases packets
can not be passed down to the device and are erroneusly dropped by the
code. It is based on commit bad6919469,
which fixes the same problem in b43.
