drm: Do not drop root privileges for a fancier younger process
When a second process opens the device and master transferrence is complete, we walk the list of open devices and remove their authentication. This also revokes our root privilege. Instead of simply dropping the authentication, this patch reverts the authenticated state back to its original value.
