      Description

      If some race happen, dentry name which we copied is invalid,
      we should return failure directly rather than continue.

      Because Server doesn't support open-by-fid, we pass @name
      as NULL, @len as 0, it will definitely trigger following
      assertion in mdc_pack_name()
