Certain properties need to release memory when destroying the NMSetting. For "direct" properties, we have all the information we need to do that generically in the NMSetting base class. In practice, this only concerns string properties. See _finalize_direct() in "nm-setting.c". However, if the NMSetting base class takes care of freeing the strings, then the subclasses must not also unref the variable (to avoid double free). Previously, subclasses had to opt-in for the base class to indicate that they are fine with that. Now, let the base class always handle it. We only need to make sure that classes that implement direct string properties don't also try to free the values during destruction.
