When we enable storage keys for a guest lazily, we reset the ACC and F values. That is correct assuming that these are 0 on a clear reset and the guest obviously has not used any key setting instruction. We also zero out the change and reference bit. This is not correct as the architecture prefers over-indication instead of under-indication for the keyless->keyed transition. This patch fixes the behaviour and always sets guest change and guest reference for all guest storage keys on the keyless -> keyed switch.
