Remove unnecessary base::Passed() with base::BindOnce()

The documentation on base::Callback<...> (src/docs/callback.md)
recommends against using base::Passed(...) with base::BindOnce.

> Avoid using `base::Passed()` with `base::BindOnce()`, as `std::move()`
> does the same thing and is more familiar.
