    sna/present: Remove stale assert that fake vblanks only have one event

    Since commit 02f535e8f3659f1147c6f2e698bd5d8730dec19b

        sna/present: Requeue early vblank completions

    we may hit the fake vblank timer path with an old hw struct that may have
    multiple associated events. The assert that we only called the fake
    vblank from sna_present_queue_vblank is no longer correct.

commit 4b4324cd059590cbeb37b6d6fd79446171cd04c4

    sna/present: Update the vblank timestamp after a blocking wait

    After doing a blocking wait (rather than event driven) for the imminent
    arrival of the next frame (when it is expected less than 1ms in the
    future), update the timestamp and frame counter that we then report back
    to present.
