voicebus: Improve hard underrun handling.
When there is a hard underrun, or in other words interrupts are held off for so
long that the board completely runs out of transmit descriptors, it was too easy
for the driver to be in a 'confused' state about the descriptors. This change
has the driver cleanup and reset the descriptor ring in this case so that we're
not racing against the interface while we resume normal operation.
