opencl: remove a self-referential macro

Henry Linjamäki · Henry Linjamäki · commit 0c5c7ba211f4 · 2025-03-28T13:19:02.000+02:00
PoCL fails to compile due to a self-referential macro in
ggml-opencl_mm.cl (`#define sub_group_reduce_add
sub_group_reduce_add`) on some devices:

```
error: /home/linehill/.cache/pocl/kcache/tempfile_qlSuTg.cl:1048:11 &lt;Spelling=/home/linehill/.cache/pocl/kcache/tempfile_qlSuTg.cl:851:30&gt;: use of undeclared identifier 'sub_group_reduce_add'
...
```
