Fix an error handling issue reported by Coverity:

  /qemu/tests/qtest/ahci-test.c: 1452 in prepare_iso()
  1444         int fd = mkstemp(cdrom_path);
  >>>     CID 1432375:  Error handling issues  (NEGATIVE_RETURNS)
  >>>     "fd" is passed to a parameter that cannot be negative.
  1452         ret = write(fd, patt, size);
