ubifs: Remove obsolete TODO from dfs_file_write()
AFAICT this kind of problems are no longer possible since debugfs gained file removal protection via e9117a5a4bf6 ("debugfs: implement per-file removal protection"). Cc: Christoph Hellwig <hch@lst.de> Cc: Nicolai Stange <nicstange@gmail.com> Signed-off-by: Richard Weinberger <richard@nod.at>
