Aleksander Morgado 6c1a6d2d5f platform: avoid storing unknown netlink object types (bgo #742928) 
Testing WWAN connections through a Nokia Series 40 phone, addresses of family
AF_PHONET end up triggering an assert() in object_has_ifindex(), just because
object_type_from_nl_object() only handles AF_INET and AF_INET6 address.

In order to avoid this kind of problems, we'll try to make sure that the object
caches kept by NM only store known object types.
