media: cedrus: hevc: Add check for invalid timestamp
Not all DPB entries will be used most of the time. Unused entries will thus have invalid timestamps. They will produce negative buffer index which is not specifically handled. This works just by chance in current code. It will even produce bogus pointer, but since it's not used, it won't do any harm. Let's fix that brittle design by skipping writing DPB entry altogether if timestamp is invalid.
