drm/amd/display: Correct timing_adjust_pending flag setting.

[Why&How]
stream->adjust will be overwritten by update->crtc_timing_adjust.
We should set update->crtc_timing_adjust->timing_adjust_pending
and then overwrite stream->adjust.
Reset update->crtc_timing_adjust->timing_adjust_pending after
the assignment.
