drm: Don't clear vblank timestamps when vblank interrupt is disabled
Clearing the timestamps causes us to send zeroed timestamps to userspace
if they get sent out in response to the drm_vblank_off(). It's better
to send the very latest timestamp and count instead.
Testcase: igt/kms_flip/modeset-vs-vblank-race
