Currently, the nested state format is hardcoded to VMX. This will result
in kvm_put_nested_state() returning an error because the KVM SVM support
checks for the nested state to be KVM_STATE_NESTED_FORMAT_SVM. As a
result, kvm_arch_put_registers() errors out early.

Update the setting of the format based on the virtualization feature:
   VMX - KVM_STATE_NESTED_FORMAT_VMX
   SVM - KVM_STATE_NESTED_FORMAT_SVM

Looks good, but what are the symptoms of this in practice?
