[igt-dev] [PATCH i-g-t] tests/kms_async_flips: Fix flip timestamp checks

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Check the flip timestamp from the event (not the time we got the
event) against the vblank timestamps. Also if things are going
well we should expect the flip timestamp to in fact match the
first vblank timestamp, so allow them to be equal.
