very minor cleanups

- add `must_use` to `early_error_no_abort`

  this was already being used at its only callsite, but this ensures that new code remembers to use it if it's called in the future. found this while investigating https://github.com/rust-lang/rust/issues/110090.

- remove outdated and incorrect comment in `builder.rs`. `doc_rust_lang_org_channel` doesn't exist in rustdoc, it gets it from an env var instead: b275d2c30b/src/librustdoc/clean/utils.rs (L569-L573)
