[xenopsd]: it's not possible to add a (VIF, VBD, PCI) to an unmanaged VM

xenopsd only does what it has been told: it will ignore "unmanaged" VMs
(VMs managed by other instances or other toolstacks). Therefore it should
also reject attempts to have it manage devices for VMs which it doesn't
manage.
