spi: spidev_test: don't send 0x0 or 0xff
Particularly when using compare mode, if the controller fails to
transfer any data, asserting on a read of 0x00 or 0xff may lead to a
false negative test, indicating a byte was successfully transferred when
the values simply originate from the pull-up or pull-down of RX.
