Replace return await promise with return promise

Awaiting a promise before returning it doesn't make sense if the await
isn't in a try/catch as awaiting forces a function to be async and thus
turns its return value and any error it might throw into a promise.
Worse than that, it can result in an unnecessary context switch which
could be bad for performance.
