[PATCH] Xi: update device state even if no emulated events are sent

[carlosg at gnome.org]

From: Carlos Garnacho <carlosg at gnome.org>

A touch sequence emulating pointer events may end up not sending
pointer events (ie. if handled completely by a passive touch grab),
but the device state needs to be updated anyway for subsequent
events to have a correct state.

This patch can be considered a leftover of 863f32c930d7
