media_module: h264 mosaics issue [1/1]

PD#OTT-7437

Problem:
Because of the video file have some error,
the decoder did not filter out some masaics frames,
result show mosaic picture.

Solution:
1.Due to the video file error, the DPB buffer is flushed
when the driver logic is wrong, resulting in the
reference frame referenced by the later frame is not
correct, result show mosaic picture, remove the error
logic to solve this problems.
2.When there are some frames lost in the video file and
have frame number gap, the reference frame relationship
will be wrong and the decoding will show mosaic picture.
In this case, the decoding of the frame will be marked
wrong, to solve this problem.
3.Resolve the error in the stream file, all the frames
except for I frame were marked as wrong frames, resulting
playback unsmooth.
