semicolon_if_nothing_returned on an attribute macro

[Gingeh]

Summary

Clippy suggests to add a semicolon after the pollster::main attribute macro. Interestingly, it doesn't trigger when the function is written on a single line.

Lint Name

semicolon_if_nothing_returned

Reproducer

I tried this code:

#[pollster::main]
async fn main() {
}

I saw this happen:

warning: consider adding a `;` to the last statement for consistent formatting
 --> src/main.rs:1:1
  |
1 | #[pollster::main]
  | ^^^^^^^^^^^^^^^^^ help: add a `;` here: `#[pollster::main];`

  = note: `-W clippy::semicolon-if-nothing-returned` implied by `-W clippy::pedantic`
  = help: to override `-W clippy::pedantic` add `#[allow(clippy::semicolon_if_nothing_returned)]`

kinda looks like the same problem I encountered in this one, now I think it might be the quote_spanned's fault lol, I'll look into it tho...
