cluster/dht: instruct marker whenever it shouldn't do accounting
This is needed for two reasons: * since dht-linkfiles are internal, they shouldn't be accounted. * hardlink handling in marker is broken. link/unlink of hardlinks present in same directory can break marker accounting. Hence, if src and dst are in same directory in case of rename, dht - if it breaks rename into link/unlink operations - should instruct marker to not to do accounting.
