WPS: Remove expired PINs on Selected Registrar timeout

This clears the AuthorizedMACs advertisement immediately when the
Selected Registrar timeout is hit and no more active PINs are present.
Previously, the AuthorizedMACs advertisement could remain in place
indefinitely since expired PINs were removed only when actually trying
to find a PIN for a new WPS exchange.
