Since order_hint_bits_minus_1 range is 0~7, cur_frame_hint can be
most 128. And similar return value for cbs_av1_get_relative_dist.
So if plus them and use int8_t for the result may lose its precision.

Hi James,
Could you help to review this version? This fixed your comments in V4.
And we tested the 3th patch with DXVA, which can also fix the clip I

Set applied.
