[libgpiod][PATCH v2 4/4] bindings: rust: clippy: silence false-positive on iterator

[Erik Schilling <erik.schilling@linaro.org>]

This was fixed on clippy master [1], but it is still broken on 0.1.70. So
lets silence it until the clippy fix is widely available.

clippy version: clippy 0.1.70 (90c5418 2023-05-31).
