    make diagnostics workable for libvirt with Xen

    When using "diagnostics" with libvirt as driver on nova-compute
    and Xen as hypervisor the call to domain.memoryStats() in
    get_diagnostics() doesn't fail with a libvirt.libvirtError,
    but with an AttributeError. This exception should be catched, too.

    The method virDomainMemoryStats is not implemented in libvirt
    for Xen.

    fixes bug 1076527
