media_module: h265 fixed same frame being written to DPB multiple times [1/1]

PD#SWPL-30901

Problem:
In stream mode, multiple frames are decoded in a decoding process,
but at last there is insufficient data. As a result, other frames
are stored in DPB except last frame. However, the next run will be
decode again and stored in DPB, which results in the same frame being
stored in DPB for many times and cause playback stuck.

Solution:
In this case, release all the frames stored in the DPB in this
decoding process to resolve this problem.

Verify:
