Fix typo in `offset_from` documentation

Small fix for what I think is a typo in the `offset_from` documentation.

Someone reading this may understand that the distance in bytes is obtained by dividing the distance by `mem::size_of::<T>()`, but here we just want to define "units of T" in terms of bytes (i.e., units of T == bytes / `mem::size_of::<T>()`).
