[op] Prevent file leak in MultiGetAttr's error path.

The old implementation was mostly correct but error prone - making way for the
issue in question here. In its error path, it would leak the intermediate file
being walked. Each return/break needed explicit cleanup.

This change implements a more clean way to cleaning up intermediate directories.
If the code were to evolve to be more complex, it would still work.
