katautils: don't do validation when loading hypervisor config

Policy for whats valid/invalid within the config varies by VMM, host,
and by silicon architecture. Let's keep katautils simple for just
translating a toml to the hypervisor config structure, and leave
validation to virtcontainers.

Without this change, we're doing duplicate validation.
