qom: Fix ambiguous path detection when ambiguous=NULL
object_resolve_path*() ambiguous path detection breaks when ambiguous==NULL and the object tree have 3 objects of the same type and only 2 of them are under the same parent. e.g.: /container/obj1 (TYPE_FOO) /container/obj2 (TYPE_FOO) /obj2 (TYPE_FOO) With the above tree, object_resolve_path_type("", TYPE_FOO, NULL) will incorrectly return /obj2, because the search inside "/container" will return NULL, and the match at "/obj2" won't be detected as ambiguous. Fix that by always calling object_resolve_partial_path() with a non-NULL ambiguous parameter. Test case included.
