drm/amd/display: fix condition for setting timing_adjust_pending

Browse Source 
timing_adjust_pending is used to defer certain programming sequences
when OTG timing is about to be changed, like with VRR. Insufficient
checking for timing change in this case caused a regression which
reduces PSR Replay residency.
