drm/amd/display: fix clock sequence logic for DCN32

[Why&How]
The newer commit sequence on DCN32 onwards did not finish clock
optimization sequence since the newer sequence did not end up calling
dc_post_update_surfaces_to_stream() which resets dc->optimized_required.

Call this function before passing control on to the new commit sequence.
