mci_spi: always compute command crc byte
The spec says: "the CMD8 CRC verification is always enabled.
The Host shall set correct CRC in the argument ofCMD8. If
CRC error is detected, card returns CRC error in R1 response
regardless of command index."
Make it simple, and compute crc on every commands.
