mmc: moxart: report DMA completion timeout

Browse source

moxart_transfer_dma() waits for the DMA completion but ignores
wait_for_completion_interruptible_timeout(). It then unconditionally
reports the full transfer length in data->bytes_xfered.

Terminate the DMA channel and set data->error when the wait is
interrupted or times out. Only report host->data_len as transferred
after the completion is observed.
