[PATCH] dix: fix calculation of valuator events.

[Peter Hutterer]

Follow-up to 4971315296cb. countValuatorEvents was copied from GKVE where it
was obviously broken but nobody noticed. GPE had the correct version, but that
one got lost during de-duplication. Restoring the correct calculation - if we
have 6 valuators, we want 1 valuator event, not 2.
