    tools/xl: fix possible uninitialized usage in printf_info()
    
    printf_info_one_json() won't initialize the passed jso_r parameter on
    error, and hence the usage in printf_info() needs prior initialization,
    otherwise an uninitialized pointer is passed to json_object_put() on
    failure.
    
    Reported by the internal XenServer Coverity instance.
    
    Fixes: f6c6f2679d49 ("libxl: Convert libxl__object_to_json() to json-c")
