Tighten the scope of the loop variables in hx711_read() now that the
trailing-pulse refactor is in place.

No functional change.

Changes in v5:
- New patch split out of the trailing-pulse refactor during review.
- Use unsigned scoped loop iterators in hx711_read().
Changes in v4:
- The scoped loop-variable cleanup was previously bundled with the
trailing-pulse patch.
