map_entry with else if and hashmap produce uncompilable code

[Freyskeyd]

Summary

The generated suggestion can't be compiled when using else if and a HashMap. I created a playground to reproduce the issue: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=acfee3c8c6ac5f68248d2317f17a1b46

Lint Name

map_entry

Reproducer

I tried this code:

        if self.pending_dial.contains_key(&peer_id) {
            println!("Key one");
        } else if peer_id != *self.swarm.local_peer_id() {
            println!("Key two");
            self.pending_dial.insert(peer_id, "sender".to_string());
        } else {
            println!("Else");
        }

I saw this happen:

I expected a compilation ready suggestion
