CTRL: Ignored a SET LINK INFO packet with real ACCMs!

That always appears and nobody has bothered to find out why, as it has
no effect on the outcome. Even I see it in testing before releasing a
new version. I'm tempted to ignore it until someone can tell me why I
shouldn't. ;-}

Shrug. We get this all the time. I see no need to fix it. Last time I
checked, it was unimportant. If you think pptpd is not complying with
the RFC in this, then we should change the message to make that clearer.
