Replace into_iter() -> iter() for arrays, fixes 1.42-nightly warning

warning: this method call currently resolves to `<&[T; N] as IntoIterator>::into_iter` (due to autoref coercions), but that might change in the future when `IntoIterator` impls for arrays are added.

    |           ^^^^^^^^^ help: use `.iter()` instead of `.into_iter()` to avoid ambiguity: `iter`
    |
    = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
