Janis Schoetterl-Glausch b62267b8b0 KVM: s390: Return error on SIDA memop on normal guest
commit 2c212e1baedcd782b2535a3f86bc491977677c0e upstream.

Refuse SIDA memops on guests which are not protected.
For normal guests, the secure instruction data address designation,
which determines the location we access, is not under control of KVM.
