[libata scsi] fix read/write translation edge cases

Fix bugs for unlikely edge cases noticed by Douglas Gilbert:

- When READ(6)/WRITE(6) sector count == 0, treat it as 256 sectors

- For other READ(x)/WRITE(x), when sector count == 0, error.
  We don't support successfully completing zero-length transfers at
  this time.
