[libvirt] PATCH: Fix bug in error reporting for security driver

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

There are a couple more bugs in the security driver error reporting
code

 - The remote daemon driver was formatting a generic string error, instead
   of sending back the actual libvirt error
 - The public interface was not raising a full error, nor copying the error
   from the connection to the global error object
