Marco Trevisan (Treviño) 45a5171a95 gdm: Filter service non-error messages on verification stopped or failed
Once the verification has been stopped or has failed all the messages
that are not of error type are just not needed or wrong to show.
For example, in the fingerprint case we may still show the hint to swipe
or touch the device, while the fingerprint PAM service has already been
stopped.

So filter them by adding a new function that adds a null message to the
queue, overriding all the messages that have a lower priority.
