soc/nvidia/tegra210: Fix potential NULL pointer dereference

Recent Coverity scan indicated potential NULL deference; if either
spi->dma_in or spi->dma_out are NULL, the fifo_error() check could
dereference a NULL pointer.

Also fixed what appears to be a logic bug for the spi->dma_out case,
where it was using the todo (count) from spi->dma_in.
