Dimitry Andric 5f2aca8394 Disable clang 14 warning about bitwise operators in zstd
Parts of zstd, used in openzfs and other places, trigger a new clang 14
-Werror warning:

```
sys/contrib/zstd/lib/decompress/huf_decompress.c:889:25: error: use of bitwise '&' with boolean operands [-Werror,-Wbitwise-instead-of-logical]
                        (BIT_reloadDStreamFast(&bitD1) == BIT_DStream_unfinished)
                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

While the warning is benign, it should ideally be fixed upstream and
then vendor-imported, but for now silence it selectively.
