clippy: Iterate without calling .iter()

See:
https://rust-lang.github.io/rust-clippy/master/index.html#explicit_iter_loop
https://rust-lang.github.io/rust-clippy/master/index.html#explicit_into_iter_loop

Before:

    for element in slice.iter() {...}

After:

    for element in slice {...}

TEST=grep -r '\.iter_mut() {'
TEST=grep -r '\.into_iter() {'
