fs: cifs: Fix atime update check

Browse Source 
Commit 9b9c5bea0b ("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 69738cfdfa ("fs: cifs: Fix atime
update check vs mtime") fixed one place and forgot to fix another. Fix it.
