GCC 14 introduces a new -Walloc-size included in -Wextra which errors out
like:
```
check.c: In function ‘cfi_alloc’:
check.c:294:33: error: allocation of insufficient size ‘1’ for type ‘struct cfi_state’ with size ‘320’ [-Werror=alloc-size]
294 | struct cfi_state *cfi = calloc(sizeof(struct cfi_state), 1);
| ^~~~~~
```
The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```
So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 struct of size `sizeof(struct ...)`. GCC then sees we're not
doing anything wrong.
