This is mainly beacause we handle ISOCH differently as compared to other transfers. Patch 1: make sure we do channel tear down only if channel is busy. If not the tear down will never succeed. Patch 2: ISOCH completions are done differently, so this might lead to reprogram of dma channel on which already a teardown is done.
