Subject: [PATCH 021/128] KVM: selftests: Use KVM_IOCTL_ERROR() for one-off
 arm64 ioctls

Use the KVM_IOCTL_ERROR() macro to generate error messages for a handful
of one-off arm64 ioctls.  The calls in question are made without an
associated struct kvm_vm/kvm_vcpu as they are used to configure those
structs, i.e. can't be easily converted to e.g. vcpu_ioctl().
