The SEND_IF_COND command (CMD8) response is of format R7, but
current code returns R1 for CMD8. Fix it.
Fixes: 775616c3ae8c ("Partial SD card SPI mode support")

When testing with VxWorks driver, this additional issue was exposed.
It looks like VxWorks has stricter parsing on command responses while
U-Boot/Linux drivers are all happy with exising QEMU CMD8 response.
