ACPI: button: Change return type of two functions to void
The return value of acpi_lid_notify_state() is always 0, so change
its return type to void.
Moreover, the return value of the only caller of that function,
acpi_lid_update_state(), is never used, so change its return type
to void either.
No intentional functional impact.
