viafb_dma_copy_out_sg() logs a VIA DMA timeout when the DONE bit is not set after the completion wait and grace delay, but still returns success to the caller. Preserve the existing cleanup sequence and return -ETIMEDOUT when the DMA engine did not report completion.

Note that the return value isn't checked by the caller. Nevertheless, it's a cleanup, so I applied it. Thanks! Helge
