rustc_codegen_ssa: Remove trailing spaces in Display impl for CguReuse

Otherwise errors will look like this:

    error: CGU-reuse for `cgu_invalidated_via_import-bar` is `PreLto ` but should be `PostLto `

### Background

I noticed that error messages looked wonky while investigating if
https://github.com/rust-lang/rust/blob/529047cfc3f4f7b3ea5aaac054408f368d153727/compiler/rustc_codegen_ssa/src/assert_module_sources.rs#L281-L287
should not be wrapped by `sess.emit_err(...)`. Right now it looks like the error is accidentally ignored. It looks like rust-lang@706452e might have accidentally started ignoring it (by removing the `diag.span_err()` call). I am still investigating, but regardless of the outcome we should fix the trailing whitespace.
