ACPI: button: Eliminate ternary operator from acpi_lid_evaluate_state()

The ternary operator in acpi_lid_evaluate_state() is not actually needed
because the same result can be achieved by applying the !! operator to
the lid_state value, so update the code accordingly.

No intentional functional impact.
