crate_in_macro_def lints on a macro use

[hkBst]

Summary

Running clippy on rustc, I got this warning:

warning: `crate` references the macro call's crate
    --> compiler/rustc_middle/src/query/mod.rs:1430:53
     |
1430 |     query region_scope_tree(def_id: DefId) -> &'tcx crate::middle::region::ScopeTree {
     |                                                     ^^^^^ help: to reference the macro definition's crate, use: `$crate`
     |
     = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#crate_in_macro_def
     = note: `-W clippy::crate-in-macro-def` implied by `-W clippy::suspicious`
     = help: to override `-W clippy::suspicious` add `#[allow(clippy::crate_in_macro_def)]`

Following this advice leads to all kinds of compiler errors. I don't understand this code well enough to understand why it is wrong, but looking at the lint docs it says:

Checks for usage of crate as opposed to $crate in a macro definition.

This hit is for a procedural macro call, not a macro definition.
