MLK-20093 VPU: A simple workaroud for vpu decoder to handle the case that some frame is not for diaplay 

If the buffer is not for display, it will be released directly by
firmware but not return the event VID_API_EVENT_FRAME_BUFF_RDY for
display, for this case, just add the buffer to the queue list again
