avcodec/cbs_av1: fix setting FrameWidth in frame_size_with_refs()

Browse Source 
Section 5.9.7 of the spec states

    UpscaledWidth = RefUpscaledWidth[ ref_frame_idx[ i ] ]
    FrameWidth    = UpscaledWidth
    FrameHeight   = RefFrameHeight[ ref_frame_idx[ i ] ]
    RenderWidth   = RefRenderWidth[ ref_frame_idx[ i ] ]
    RenderHeight  = RefRenderHeight[ ref_frame_idx[ i ] ]

Meaning FrameWidth must not be set to RefFrameWidth[ ref_frame_idx[ i ] ]
like we're currently doing.
