Dosen't num_cpuid_config serve as temporary variable in some sense?
For this case, it needs to be used for calculating the size of tdx_info.
So we have to have it. But it's not the common case.
E.g., if we have another non-u64 field (e.g., field_x) in tdx_info, we
cannot to read it via
tdx_sys_metadata_field_read(FIELD_X_ID, &tdx_info->field_x);
we have to use a temporary u64 variable.
