Let's also properly forward that bit. It should always be set. I
verified it under z/VM, it seems to be always set there. For now,
zKVM guests never get that bit set when the CPU model is active.

The PoP mentiones, that z800 + z900 (HW generation 7) always set this
bit to 0, so let's take care of that.
