During tsif stress tests it was reported that the dma flush caused by calling action_close() is sometimes unrecoverable. The root cause is stopping the tsif while a read by the dma of the tsif FIFO is in progress. This workaround works by starving the tsif FIFO allowing any in-flight transfers to complete, and thus ensuring a clean shutdown.
