For multi-core jpegdec, the all hws may run at the same time, if one hw decoded firstly, the function of mtk_jpeg_dec_stop_streaming would be called, but others input buffers are decoding, this will cause some running buffers to be buffer done, causing errors; 2. add a parameter to calculate the decoding buffer counts, it wil decrease to 0 until the all buffers decoded and the mtk_jpeg_dec_stop_streaming could continue to be executed.
