[PATCH] dix: extend IsPointerDevice check to valuator-only devices.

[Peter Hutterer]

A device with valuators but no keys is definitely a pointer device and needs
to be attached to the VCP. Otherwise, the class copying happens on the VCK
and the VCP isn't updated with the events that are to be sent through it.
This addresses the trigger for #24441, not the actual issue.
Jury is still out on valuator+key devices.
