usb: Convert uses of usb_create()

Replace

    dev = usb_create(bus, type_name);
    ...
    object_property_set_bool(OBJECT(dev), true, "realized", &err);

by

    dev = isa_new(type_name);
    ...
    usb_realize_and_unref(dev, bus, &err);

Recent commit "qdev: New qdev_new(), qdev_realize(), etc." explains
why.
