Let's accept KVM_CLOCK_HOST_TSC here even though it's not used; there
may be programs that expect to send back to KVM_SET_CLOCK whatever they
got from KVM_GET_CLOCK.

Nevermind, KVM_SET_CLOCK is already rejecting KVM_CLOCK_TSC_STABLE so no
need to do that!

Yeah, I don't know the story on the interface but it is really odd
that userspace needs to blow away flags to successfully write the
clock structure.
