    libxl: Fix device_add QMP calls with QEMU 9.2 and newer
    
    QEMU used to ignore JSON types and do conversion string <-> integer
    automatically for the command "device_add", but that was removed in
    QEMU 9.2 (428d1789df91 ("docs/about: Belatedly document tightening of
    QMP device_add checking")).
    
    Fixes: 9718ab394d5d ("libxl_usb: Make libxl__device_usbctrl_add uses 
ev_qmp")
    Fixes: 40c7eca10a82 ("libxl_usb: Make libxl__device_usbdev_add uses ev_qmp")
