gdm: unconditionally cancel auth user verifier on reset

We currently only cancel the user verifier on reset if
verifying, but that means we don't properly cancel it when
asking for a username at the Not Listed screen.

The object already handles getting called when there is
nothing to cancel, so just cancel it unconditionally.
