[PATCH 18/21] drm/amd/display: Avoid force minimal transaction in case of surface_count equal to 0.

[Pavle Kotarac]

From: JeromeHong <jerome.h...@amd.com>

[why]
Call commit_minimal_transition_state wrongly in case of surface_count equal to 
0.

[how]
Add a condition to filter case of surface_count equal to 0.
