spi: rspi: Fix loopback mode for Dual/Quad SPI Transfers While normal Dual and Quad SPI Transfers are unidirectional, we must do a bidirectional transfer if loopback mode is enabled, else rx_buf is not filled. With spidev it seemed to work, as spidev uses the same buffer for tranmission and reception.
