[libvirt] [PATCH v2 03/11] interface: Use virInterfaceDefPtr rather than deref from virInterfaceObjPtr



We're about to make the obj much more private, so make it easier to
see future changes which will require accessors for the obj->def

This also includes modifying some interfaces->objs[i]->X references to be
obj = interfaces->objs[i]; and then def = obj->def
