[committed hurd 1/2] libdiskfs: fix renaming of directories

[Justus Winter]

Previously, file permissions and ownership of the target directory
were ignored when renaming a directory:

    % mkdir a b
    % chmod 555 a
    % mv b a
    % ls a
    b

* libdiskfs/dir-renamed.c (diskfs_rename_dir): Fix error handling.
