soc/nvidia/tegra124: Fix null pointer and logic bug

Commit 680027edf6 fixed a null dereference and logic bug in the tegra210
spi code:

    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.

Coverity is warning about the same problem for tegra124, so apply the
same fix there. Also, add braces around a while statement.
