xenserver: Improve xsconsole plugin in various ways.

- xapi now takes care of syncing the setting to all host so no need to
  do that manually.
- Set controller to "" to unset.
- No need to display ovs-brcompatd status since it is disabled.
- Do not raise XenAPIPlugin.Failure, it is not an exception xsconsole
  will handle.
