dmaengine: cppi41: fix cppi41_dma_tx_status() logic
It makes sense to set residue when channel is in progress. Otherwise it should be 0 since transfer is completed. Meanwhile this patch doesn't prevent to set residue value anyway. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
