Re: [PATCH 0/1] MR2892: wined3d: Fix uninitialized variable warning.

[Davide Beatrici (＠davidebeatrici)]

```c
../dlls/wined3d/context_vk.c:2346:32: error: 'a' may be used uninitialized in this function [-Werror=maybe-uninitialized]
 2346 |                     a->binding = i;
      |                     ~~~~~~~~~~~^~~
```

I don't see this warning locally, but I just realized `a` is in a `for` loop right below.
