ASoC: Intel: catpt: Test dmaengine_submit() result before moving on
[ Upstream commit 2a9a72e290d4a4741e673f86b9fba9bfb319786d ]
After calling dmaengine_submit(), the submitted transfer descriptor
belongs to the DMA engine. Pointer to that descriptor may no longer be
valid after the call and should be tested before awaiting transfer
completion.
