libxl currently refuses to execute hotplug scripts if the backend domid of a device is different than LIBXL_TOOLSTACK_DOMID. This will prevent libxl from executing hotplug scripts when running on a domain different than LIBXL_TOOLSTACK_DOMID, we should instead check if backend_domid is different than current domid.
