fs: cifs: Fix atime update check vs mtime
commit 69738cfdfa7032f45d9e7462d24490e61cf163dd upstream.
According to the comment in the code and commit log, some apps
expect atime >= mtime; but the introduced code results in
atime==mtime. Fix the comparison to guard against atime<mtime.
Fixes: 9b9c5bea0b96 ("cifs: do not return atime less than mtime")
