allow() fails when other warnings trigger (possibly on macro)

Summary

When a statement (macro?) triggers two different warnings and one of them is allow-ed, the allow-ed warning triggers anyway

Reproducer

I tried this code:

    #[allow(clippy::write_with_newline)]
    write!(w, "{}\n", val);

I saw this happen:

warning: unused attribute `allow`
  --> src/lib.rs:9:5
   |
9  |     #[allow(clippy::write_with_newline)]
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
note: the built-in attribute `allow` will be ignored, since it's applied to the macro invocation `write`
  --> src/lib.rs:10:5
   |
10 |     write!(w, "{}\n", val);
   |     ^^^^^
   = note: `#[warn(unused_attributes)]` on by default

warning: using `write!()` with a format string that ends in a single newline
  --> src/lib.rs:10:5
   |
10 |     write!(w, "{}\n", val);
   |     ^^^^^^^^^^^^^^^^^^^^^^
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#write_with_newline
   = note: `#[warn(clippy::write_with_newline)]` on by default
help: use `writeln!` instead
   |
10 -     write!(w, "{}\n", val);
10 +     writeln!(w, "{}", val);
   |

warning: unused `std::result::Result` that must be used
  --> src/lib.rs:10:5
   |
10 |     write!(w, "{}\n", val);
   |     ^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: this `Result` may be an `Err` variant, which should be handled
   = note: `#[warn(unused_must_use)]` on by default
   = note: this warning originates in the macro `write` (in Nightly builds, run with -Z macro-backtrace for more info)

I expected to see this happen:

warning: unused `std::result::Result` that must be used
  --> src/lib.rs:10:5
   |
10 |     write!(w, "{}\n", val);
   |     ^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: this `Result` may be an `Err` variant, which should be handled
   = note: `#[warn(unused_must_use)]` on by default
   = note: this warning originates in the macro `write` (in Nightly builds, run with -Z macro-backtrace for more info)

The version which does not trigger unused_must_use:

    #[allow(clippy::write_with_newline)]
    write!(w, "{}\n", val).unwrap();

does not trigger any warning

No response

Start with the Rust reproducer using write! and #[allow(clippy::write_with_newline)], comparing the diagnostics with and without .unwrap(). Investigate how the Clippy lint and the unused attribute, unused_must_use, and macro invocation interact; done when allowing write_with_newline suppresses that lint without suppressing the unrelated unused_must_use warning.
