Error out early on an expired token 

Fixes #12131

If we hit an expired token there is no need to continue checking. Since
we know it is a token.

We also should not register this with the bruteforce throttler as it is
actually a valid token. Just expired. Instead the authentication should
fail. And buisness continues as usual.
