[PATCH] dmaengine: ti: edma: Fix reference count leaks due to pm_runtime_get_sync

On calling pm_runtime_get_sync() the reference count of the device
is incremented. In case of failure, should decrement the reference
count before returning the error. So we fixed it by replacing it
with pm_runtime_resume_and_get.
