vz: Unify vzDomObjFromDomain{Ref} 

Rather than have two API's doing different things for different
callers, let's make one API that will always return a locked and
ref counted object. That way, the callers will always know that
they must call virDomainObjEndAPI and not have to decide whether
they should call virObjectUnlock instead.

This will make things consistent with LookupByName which returns
the locked and ref counted object.
