skd: fix unchecked return values
Check return values of dma_set_mask_and_coherent().
Otherwise, if dma_set_mask_and_coherent(&pdev->dev, DMA_BIT_MASK(64));
fails, the following piece of code will be executed even when the call
to dma_set_mask_and_coherent(&pdev->dev, DMA_BIT_MASK(32)); returns 0:
dev_err(&pdev->dev, "DMA mask error %d\n", rc);
goto err_out_regions;
Addresses-Coverity-ID: 1474553 ("Unchecked return value")
Fixes: 138126214868 ("skd: switch to the generic DMA API")
