    virtio: Drop broken and superfluous object_property_set_link()
    
    virtio_crypto_pci_realize() and copies the value of vcrypto->vdev's
    property "cryptodev" to vcrypto's property:
    
        object_property_set_link(OBJECT(vrng), "rng", 
OBJECT(vrng->vdev.conf.rng),
                                 NULL);
    
    Since it does so only after realize, this always fails, but the error
    is ignored.
    
    It's actually superfluous: vcrypto's property is an alias of
    vcrypto->vdev's property, created by virtio_instance_init_common().
    
    Drop the call.
    
    Same for virtio_ccw_crypto_realize(), virtio_rng_pci_realize(),
    virtio_ccw_rng_realize().
