Fix extra `non_snake_case` warning for shorthand field bindings

Fixes rust-lang#89469. The problem is the innermost `if` condition here:
https://github.com/rust-lang/rust/blob/d14731cb3ced8318d7fc83cbe838f0e7f2fb3b40/compiler/rustc_lint/src/nonstandard_style.rs#L435-L452

This code runs for every `PatKind::Binding`, so if a struct has multiple fields, say A and B, and both are bound in a pattern using shorthands, the call to `self.check_snake_case()` will indeed be skipped in the `check_pat()` call for `A`; but when `check_pat()` is called for `B`, the loop will still iterate over `A`, and `field.ident (= A) != ident (= B)` will be true. I have fixed this by only looking at non-shorthand bindings, and only the binding that `check_pat()` was actually called for.
