The dma_sync_sg_for_device() functions should be called with the same
nents as the dma_map_sg(), not the value the map function returned
according to the documentation in Documentation/core-api/dma-api.rst:450:
With the sync_sg API, all the parameters must be the same
as those passed into the sg mapping API.
