ideapad_laptop: convert internal function calls to use ideapad_private as parameter
ideapad_laptop: convert internal function calls to use ideapad_private as parameter

As struct ideapad_private has all the information needed for any operations,
convert ideapad_register_rfkill()/ideapad_unregister_rfkill() and
ideapad_sync_touchpad_state() to use struct ideapad_private as the parameter,
to be consistent with the others.
