Features defined in versioned CPU model are recorded in env->user_features
since they are updated as property. It's unwated because they are not
user specified.
Simply clear env->user_features as a fix. It won't clear user specified
features because user specified features are filled to
env->user_features later in x86_cpu_expand_features().
