dix: clean up accel old scheme data when switching schemes.

InitValuatorClassDeviceStruct always initializes with the default profile.
The default profile allocs data and adds a few properties which become
obsolete if the profile is changed lateron by the driver.

The property handlers are stored in the device's devPrivates and cleaned up.
Ideally, the property handler ID's could be stored somewhere more obvious,
but that seems to require breaking the ABI.
