Subject: [PATCH] ubifs: fix RENAME_WHITEOUT support
Remove faulty leftover check in do_rename(), apparently introduced in a
merge that combined whiteout support changes with commit f03b8ad8d386
("fs: support RENAME_NOREPLACE for local filesystems")
Fixes: 9e0a1fff8db5 ("ubifs: Implement RENAME_WHITEOUT")
