Rollup merge of #154551 - chenyukang:yukang-fix-146204-assert-ne-suggestion-span, r=JohnTitor

Skip suggestions pointing to macro def for assert_eq

Fixes rust-lang/rust#146204

It's better to suggest:
```console
help: consider borrowing here
 --> src/main.rs:3:16
  |
 3|      assert_ne!(&buf, b"----");
  |                 +
```
but i don't want to give a too heuristic but not general enough fix, let suppress them.
