Jiasheng Jiang e52dfd2a49 dmaengine: sh: rcar-dmac: Check for error num after setting mask 
commit 2d21543efe332cd8c8f212fb7d365bc8b0690bfa upstream.

Because of the possible failure of the dma_supported(), the
dma_set_mask_and_coherent() may return error num.
Therefore, it should be better to check it and return the error if
fails.
