Subject: [PATCH] drm/amd/display: Update stream adjust in
 dc_stream_adjust_vmin_vmax

commit 346d8a0a3c91888a412c2735d69daa09c00f0203 upstream.

[Why]
After v_total_min and max are updated in vrr structure, the changes are
not reflected in stream adjust. When these values are read from stream
adjust it does not reflect the actual state of the system.

[How]
Set stream adjust values equal to vrr adjust values after vrr adjust
values are updated.
