dmaengine: Revert "dmaengine: shdma: Fix runtime PM imbalance on error" 



commit d143f939a95696d38ff800ada14402fa50ebbd6c upstream.

This reverts commit 455896c53d5b ("dmaengine: shdma: Fix runtime PM
imbalance on error") as the patch wrongly reduced the count on error and
did not bail out. So drop the count by reverting the patch .
