drm_hwcomposer: Remove redundant vsync timestamp Vsync timestamp was being tracked in two values. One was used for approximating the next timestamp when waiting for vblank failed, and the other was used when vsync timestamp tracking was enabled. Add a new bool to track whether a vsync has been recorded since a caller enabled vsync timestamp tracking, and return the value of vsync_timestamp_ if it is fresh.
