description:
tools/xend: move assert to exception block

The two assert in restore trigger sometimes after hundreds of
migrations. If they trigger the destination host will not destroy the
newly created, still empty guest. After a second migration attempt to
this host there will be two guets with the same name and uuid. This
situation is poorly handled by the xm tools.
With this change the guest will be destroyed.
