Z3 commit message: [code-simplifier] Simplify `api_ast.cpp` by removing unreachable branch and stray comment (#9570)

This change simplifies recently touched API code in
`src/api/api_ast.cpp` without altering semantics. It removes an
unreachable error path in `Z3_get_index_value` and deletes an empty
comment in `Z3_mk_rec_func_decl`.

- **`Z3_get_index_value`: remove dead branch**
- After validating `a` is non-null and of kind `AST_VAR`, the conversion
to `var*` is already guaranteed by existing AST casting invariants.
- The redundant null-check/error-return branch was removed, leaving a
direct index return.

- **`Z3_mk_rec_func_decl`: remove noise**
  - Deleted a stray empty `//` line.

```cpp
// before
var* va = to_var(_a);
if (va) {
    return va->get_idx();
}
SET_ERROR_CODE(Z3_INVALID_ARG, nullptr);
return 0;

// after
var* va = to_var(_a);
return va->get_idx();
```
