When ext4_rename performs a directory rename (move), dir_bh is a buffer that is modified to update the '..' link in the directory being moved (old_inode). However, ext4_handle_dirty_metadata is called with the old parent directory inode (old_dir) and dir_bh, which is incorrect because dir_bh does not belong to the parent inode. Fix this error.
