    Fix compilation of libvirt against xen-unstable
    
    * src/xen/xen_hypervisor.c: xen-unstable changeset 19788 removed
      MAX_VIRT_CPUS from public headers, breaking compilation of libvirt
      on -unstable.  Its semanitc was retained with XEN_LEGACY_MAX_VCPUS.
      Ensure MAX_VIRT_CPUS is defined accordingly.
