spi/spi_mpc8xxx: fix potential memory corruption.
tx_dma/rx_dma are already set to a dummy buffer when no
tx/rx buffer and t->tx_dma/t->rx_dma does not contain a dma
address, but NULL.
This may lead to corruption of kernel memory. Fix this by
leaving tx_dma/rx_dma alone.
Do not INIT_TX_RX while controller is enabled, this is bad according
to the MPC8321 manual.
