`manual_div_ceil`: fix suggestions when macro is involved (#14666)

here is my small fix

changelog: fix suggestion span to avoid showing macro name in
`.div_ceil()` suggestion

i changed this line
`let divisor_snippet = snippet_with_applicability(cx,
rhs.spansource_callsite(), "..", applicability);`
to this line
`let divisor_snippet = snippet_with_applicability(cx, rhs.span, "..",
applicability);`
to fix problem where this warning in macro expands like this
```rust
4  |         let _ = (x + 7) / 8;
   |                 ^^^^^^^^^^^ help: consider using `.div_ceil()`: `x.div_ceil(y!())`
```
[play it
yourself](https://play.rust-lang.org/?version=stable&mode=debug&edition=2024&gist=397aa8cd2ffffb24a286fbddbc75446c)

as you can see here it looks like `x.div_ceil(y!())` and contains macro
signature
so i fixed this problem, i will look closely if there any more problems
like this and fix them in order
