ubifs: rename_whiteout: correct old_dir size computing
commit 705757274599e2e064dd3054aabc74e8af31a095 upstream.
When renaming the whiteout file, the old whiteout file is not deleted.
Therefore, we add the old dentry size to the old dir like XFS.
Otherwise, an error may be reported due to `fscki->calc_sz != fscki->size`
in check_indes.
