Re: [libvirt] [PATCH v3 07/20] tests: Improve result handling in cpuTestGuestData()

A test is considered successful if the obtained result matches the expected result: if that's not the case, whether because a test that was expected to succeed failed or because a test that was supposed to fail succeeded, then something's not right and we want the user to know about this. On the other hand, if a failure that's unrelated to the bits we're testing occurs, then the user should be notified even if the test was expected to fail. Use different values to tell these two situations apart. Fix a test case that was wrongly expected to fail as well.
