    qdev: Fix device_add DRIVER,help to print to monitor
    
    Help on device properties gets printed to stdout instead of the
    monitor.  If you have the monitor anywhere else, no help for you.
    Broken when commit e1043d674d "qdev: use object_property_help()"
    accidentally switched from qemu_printf() to printf().  Switch right
    back.
