Merge #4741
4741: Fix type inference failure when built with log/kv_unstable r=flodiebold a=dtolnay
This code is broken by an `impl From<kv::Error> for fmt::Error` in the log crate when building in a codebase that has the log/kv_unstable feature enabled.
```console
$ cargo check --manifest-path crates/ra_hir_def/Cargo.toml

error[E0282]: type annotations needed for the closure `fn(&str) -> std::result::Result<(), _>`
--> crates/ra_hir_def/src/path.rs:278:17
|
278 | f.write_str("::")?;
| ^^^^^^^^^^^^^^^^^^ cannot infer type
|
help: give this closure an explicit return type without `_` placeholders
|
276 | let mut add_segment = |s| -> std::result::Result<(), _> {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
