Issue: During multi threaded testing, there are cases where EDMA HW enters stopped state even through there are pending descriptors to process. This happens even when doorbell is rung after updating descriptors and barriers places. Fix: After processing channel interrupt, ring doorbell, if there are pending descriptors and for that channel is not running.
