buspirate_spi: Use non-zero return value from buspirate_sendrecv
Return values for buspirate_sendrecv come from serialport_write
and serialport_read, and those return 1s for any error. No need
to explicity assign ret = 1, because it is already 1 for error.
Follow up on commit 751afa88a7f22487069665c5d206ae490f158231
where this idea was suggested.
