Avoid partial authentication state when using --disabled in CCD configs

Avoid partial authentication state when using --disabled in CCD configs

If an openvpn server is configured with --client-config-dir and a client
configuration file contains 'disabled', it is supposed to tell the client
it is not authorized to use the service.

This patch will ensure that the internal state in this scenario is a
complete CAS_FAILED state, and not CAS_PARTIAL if other authorization
steps passed.
