orangefs: clean up truncate ctime and mtime setting
The ctime and mtime are always updated on a successful ftruncate and only updated on a successful truncate where the size changed. We handle the ``if the size changed'' bit. This matches FUSE's behavior. Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
