drm/amd/display: Fix white screen on boot with OLED panel

Browse source

[Why]
During mode change, replay_event_general_ui may remain set on the old
stream while replay_event_hw_programming is set. This can re-enable
Replay too early before hardware programming is complete.

[How]
Clear replay_event_general_ui in the mode-change path when setting
replay_event_hw_programming to keep Replay blocked until programming
finishes, avoiding white screen on OLED panels after boot.
