    Reset num_active_touches on DeviceOff (#52496)
    
    When disabling the device, reset num_active_touches to zero. Otherwise,
    num_active_touches stays at the value it was on DeviceOff(). Future touches
    add to that value until the index may go past priv->open_slots[].
    That causes spurious memory corruption on touch ends.
    
    And as of 55fc42e7c9b4948cadd4f98ef7b6a3b12e268e3e we ignore pre-existing
    touches anyway.
    
    Test-case:
    - place num_touches fingers on the touchpad
    - xinput disable <device>
    - lift fingers
    - xinput enable <device>
    - place finger on device, num_active_touches is now (num_touches + 1)
