Fix multi-display flickering.

There was a change in surfaceflinger that asks hwc to setColorTransform
for each display when displays are added/changed/removed. For some
reason, we were falling back to client composition when the display had
color transform set. Removing that fallback fixes the flickering.

Bug: 324295392
Test: Boot gcar image, see no flickering.
