So the backend knows the usage of model is for frame processing,
detect, classify, etc. Each function type has different behavior
in backend when handling the input/output data of the model.

once we mark done for the task in function infer_completion_callback,
the task is possible to be release in function ff_dnn_get_async_result_ov
in another thread just after it, so we need to record request queue
first, instead of using task->ov_model->request_queue later.

t image size is 2048x1536, so the two bounding
boxese in the original image are
(330/672*2048=1006, 203/384*1536=812) -> (1085, 904) and
(887, 836) -> (966, 924), and we can check them manually.
