platform/x86: lenovo-yogabook: Fix work race on remove()

Browse source

When yogabook_wmi_remove() runs yogabook_wmi_work might still be running
and using the devices which yogabook_wmi_remove() puts.

To avoid this move to explicitly cancelling the work rather then using
devm_work_autocancel().

This requires also making the yogabook_backside_hall_irq handler non
devm managed, so that it cannot re-queue the work while
yogabook_wmi_remove() runs.
