drm_hwcomposer: Save the atomic_test result between tests
Previously, we would only test the first frame when the geometry
changed. However, if SF sent us the same composition with different
FBs, we could end up sending invalid frames to the kernel.
This change saves the result of the atomic_test between geometry
changes so we avoid using hw composition for all invalid frames.
Bug: 25866352
Test: Tested on smaug, observed squashes between geometry changes
