Also backup and restore the original ctxt->node value in x86FeatureLoad.

Although this function is expected to change ctxt->node so the caller sets it
to its original value after x86FeatureLoad returns. But this can't hurt.
Good catch with VIR_FREE(nodes), I forgot to do so.

So far we are trying to keep this preserved by function calls, this
is way easier to track.
