selftests: kvm: Check whether SIDA memop fails for normal guests

Browse source

Commit 2c212e1bae ("KVM: s390: Return error on SIDA memop on normal
guest") fixed the behavior of the SIDA memops for normal guests. It
would be nice to have a way to test whether the current kernel has
the fix applied or not. Thus add a check to the KVM selftests for
these two memops.
