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

Browse source 
commit d143f939a9 upstream.

This reverts commit 455896c53d ("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 .
