sf: stmicro: dont send 4 bytes when reading status register
I can't find anywhere in the datasheet that says the status register needs
3 dummy bytes sent to it before being able to read back the first real
result. Tests on a Blackfin board show that after writing the opcode, the
status register starts coming back immediately. So only write out the
read status register opcode before polling the result.
