rustdoc: Prevent auto/blanket impl retrieval if there were compiler errors

Fixes rust-lang/rust#105404.

I'm not sure happy about this fix but since it's how passes work (ie, even if there are errors, it runs all passes), I think it's fine as is.

Just as a sidenote: I also gave a try to prevent running all passes in case there were compiler errors but then a lot of rustdoc tests were failing so I went for this fix instead.
