Indeed, it would be easier to use the existing cpuid data in struct

Why is KVM_SET_CPUID2 not enough? Are there any modifications done by
KVM that affect the measurement?
Then we get the situation that KVM_TDX_INIT_VM must be called after 1
vcpu is created. It seems illogical that it has chance to fail the VM
scope initialization after 1 vcpu is successfully created.
I see. Yeah, it makes sense to have the CPUID in KVM_TDX_INIT_VM then.
