ACPI: button: Fix lid_device value leak past driver removal
Static variable lid_device is set when the ACPI button driver probes
the last lid device (under the assumptions that there will be only
one lid device in the system) and never cleared, but in principle it
should be reset when the driver unbinds from the lid device pointed
to by it.
Address that and add locking that is needed to clear and set that
variable safely.
