Remove 'async' from async_tests in display-lock/

Passing an async function to async_test will soon be disallowed in WPT,
as any asserts thrown will be turned into unhandled promise rejections
and the test will timeout. If a test needs async functions it should use
promise_test instead - however in this case the tests don't actually
need async functions (they don't use await or rely on promises).
