posix/ctime: Fix updating mtime to older time
With ctime feature enabled, the mtime is not updated when it's set to time older than the existing one. Fixed the same. But the ctime is not allowed to change to older dates. fixes: bz#1581035 Change-Id: If520922df42d6ce084c8df3046c138f8367164e5 Signed-off-by: Kotresh HR <khiremat@redhat.com>
