    libvirt: ignore deleted domain while get block dev

    The get_all_block_devices could raise libvirtError if domain was deleted
    while listing instances. This will cause LibvirtISCSIVolumeDriver to fail
    disconnect_volume. This patch ignores the domain that could not be found
    to avoid this issue.

    Fixes bug 1060836
