Ricardo Ribalda Delgado 34093cb97a spi/xilinx: Fix access invalid memory on xilinx_spi_tx ...

On 1 and 2 bytes per word, the transfer of the 3 last bytes will access
memory outside tx_ptr.

Although this has not trigger any error on real hardware, we should
better fix this.

Fixes: 24ba5e593f (Remove rx_fn and tx_fn pointer)
