    libvirt: Prevent block live migration with tunnelled flag
    
    libvirt will report "Selecting disks to migrate is not
    implemented for tunneled migration" while doing block migration
    with VIR_MIGRATE_TUNNELLED flag.
    
    This patch does 2 changes:
    
    1. Raise exception.MigrationPreCheckError if block live migration with
       with mapped volumes and tunnelled flag on.
    2. Remove migrate_disks from params of migrateToURI3 in case of
       tunnelled block live migration w/o mapped volumes since we want
       to copy all disks to destination
