Commit 1ea0d3b46798 ("platform/x86: asus-wmi: Simplify tablet-mode-switch
handling") unified the asus-wmi tablet-switch handling, but it did not take
into account that the value returned for the kbd_dock_devid WMI method is
inverted where as the other ones are not inverted.
This causes asus-wmi to report an inverted tablet-switch state for devices
which use the kbd_dock_devid, which causes libinput to ignore touchpad
events while the affected T10x model 2-in-1s are docked.
Add inverting of the return value in the kbd_dock_devid case to fix this.
