[rustdoc] `jump-to-def` invalid link generated with `#[rustc_allow_incoherent_impl]`

Can be reproduced with this code (each crate depend on the previous one):

baz.rs:

#![feature(rustc_attrs)]
#![allow(internal_features)]

#[rustc_has_incoherent_inherent_impls]
pub struct Error;

bar.rs:

#![feature(rustc_attrs)]
#![allow(internal_features)]

pub mod error {
    pub use baz::Error;
}

impl baz::Error {
    #[rustc_allow_incoherent_impl]
    pub fn new() -> Self {
        Self
    }
}

lib.rs:

fn foo() {
    let x = bar::error::Error::new();
}

When generating docs with --generate-link-to-definition, the link for the Error::new method points to ../../bar/struct.Error.html#method.new, but that's the path for baz::Error, not for bar::Error.
