Marc Kleine-Budde b0f0c761ed spi: spi-fsl-lpspi: directly return ret in fsl_lpspi_transfer_one() ...

Both fsl_lpspi_dma_transfer() and fsl_lpspi_pio_transfer() only return
negative error values in case of error or 0 in case of success.

Directly return ret, there is no need to check for positive error values
and return them as 0.
