## Message

```
Fix warning WasmMut_toC not all control paths return a value (#24267)

* Fix warning WasmMut_toC not all control paths return a value

This is a follow up to https://github.com/ziglang/zig/pull/24206 where
I had previously submitted different mechanisms to fix this warning.
This PR is a suggestion by Alex to return NULL instead and Andrew
confirmed this is his preference.
