Review Comment:
The bug is that this doesn't take into account any offset that indices may have, it should be
```
buffer_bin_and(buffer, indices.offset(), &null_buf.into(), 0, data_len)
```
However, this code is completely redundant as we already check the validity of indices in the loop above when constructing this mask, and so we can just remove this
