Keep virtual core pointer touch class around if new slave doesn't have one
The VCP may have active touch grabs. The touch records must be kept so these touch grabs may be accepted/rejected in the future. This means the touch class list will not represent the touch class of the attached slave device if it does not have a touch class, but we already were breaking that assumption by keeping a separate touches array for the VCP.
