When copying to the latency type, we should be passing LATENCY_TYPE_LEN,
not DOMAIN_LEN. This isn't a problem in practice because we only pass
"total" or "I/O", but let's fix it.

Can both strlcpy() invocations be changed such that the third argument
is a sizeof() expression instead of an explicit constant? I think that
would make the Kyber tracing code easier to verify for humans.
Thanks,
