That one was left behind only because Eric couldn't spare the time to figure out whether making it strict would break anything, with a TODO comment. Time to resolve it. Strict makes a difference only for otherwise successful visits of QAPI structs or unions. Let's examine what the callers of object_property_set_qobject() visit: * object_property_set_str(), object_property_set_bool(), object_property_set_int() visit a QString, QBool, QInt, respectively. Strictness can't matter. * qmp_qom_set visits its @value argument. Comes straight from QMP and can be anything ('any' in the QAPI schema). Strictness matters when the property's set() method visits a struct or union QAPI type. No such methods exist, thus switching to strict can't break anything. If we acquire such methods in the future, we'll *want* the visitor to be strict, so that unexpected members get rejected as they should be. Switch to strict.
