fbdev: viafb: return an error when DMA copy times out

Browse source

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.
