Whenever LIC fails instead of moving from ENABLED to DESIRED
CP property we directly enable HDCP without informing the userspace
of this failure in link integrity check.
Now we will just update the value to DESIRED send the event to
userspace and then continue with the normal flow of HDCP enablement.
