ubifs: rename_whiteout: correct old_dir size computing
commit7057572745
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. Fixes:9e0a1fff8d
