Newer gcc compiler (version 16.0.0 20260103 (Red Hat 16.0.0-0) (GCC))
detects an unused variable error:

  ../tests/qtest/libqtest.c: In function ‘qtest_qom_has_concrete_type’:
  ../tests/qtest/libqtest.c:1044:9: error: variable ‘idx’ set but not used 
[-Werror=unused-but-set-variable=]

Remove idx.
