I couldn't see another loop condition that made sense to use, so I've added an
assert below:
```
assert(tags_read && (tags_read <= num_tags));
```
If num_tags was 0 we'd never enter the loop in the first place. Then we assert
that if there was no error, the kernel returned at least 1 tag and no more tags
than we asked for.
This should prevent num_tags wrapping around 0 and causing an infinite loop.
