If e.g., an [Address] section has an invalid setting, then previously assigned settings in the section is freed, and only later settings are stored. That may cause partially broken section stored in Network object. This makes if an invalid setting is found, then set 'invalid' flag instead of freeing it. And invalid sections are dropped later by network_verify().
