        * fs/hfsplus.c (grub_hfsplus_read_block): Fixed a memory leak.
        (grub_hfsplus_iterate_dir): Reordered to skip unknown nodes. Also,
        skip a node whose name is obviously invalid as UTF-16,
        i.e. contains a NUL character. Stop the iteration when the last
        directory entry is found. Instead of using the return value of
        grub_hfsplus_btree_iterate_node, store the value in RET and use
        it, because the iterator can be stopped by the last directory
        entry.
