drm/v3d/v3d_drv: Check for error num after setting mask
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.
Also, we can create a variable for the mask to solve the
alignment issue.
