I checked, and we appear to allow that for no_sanitize deliberately as well
(and in the kernel code we actually use `no_sanitize("address")` and not
`no_sanitize("kernel-address")`).
For consistency, I think we have to allow the interchangeable behaviour. I
added a comment above to refer to the no_sanitize attribute.
