Subject: [PATCH] fs: cifs: Fix atime update check

Commit 9b9c5bea0b96 ("cifs: do not return atime less than mtime") indicates that in cifs, if atime is less than mtime, some apps will break. Therefore, it introduce a function to compare this two variables in two places where atime is updated. If atime is less than mtime, update it to mtime.

However, the patch was handled incorrectly, resulting in atime and mtime being exactly equal. A previous commit 69738cfdfa70 ("fs: cifs: Fix atime update check vs mtime") fixed one place and forgot to fix another. Fix it.
