drm/amd/display: Fix DP MST timeslot issue when fallback happened
[Why]
When USB4 DP link training failed and fell back to lower link rate,
the time slot calculation uses the verified_link_cap.
And the verified_link_cap was not updated to the new one.
It caused the wrong VC payload time-slot was allocated.
[How]
Updated verified_link_cap with the new one from cur_link_settings
after the LT completes successfully.
