[PATCH 2/7] fs: cifs: Fix atime update check vs mtime

[Deepa Dinamani]

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")
