Aurabindo Pillai 0788273bd0 drm/amd/display: Fix hang when skipping modeset
commit da5e14909776edea4462672fb4a3007802d262e7 upstream.

[Why&How]

When skipping full modeset since the only state change was a front porch
change, the DC commit sequence requires extra checks to handle non
existant plane states being asked to be removed from context.
