Peter Krempa b17fd211e2 testQEMUSchemaValidateCommand: Add possibility for partial QMP validation
The QMP schema for 'device_add' is not complete yet. Allow validation of
incomplete schema so that we can enable at least some validation. Once
there's more schema in the future all present members are still
validated.
