Subject: [PATCH] s390/mcck: fix invalid KVM guest condition check

Wrong condition check is used to decide if a machine check hit while in KVM guest. As result of this check the instruction following the SIE critical section might be considered as still in KVM guest and _CIF_MCCK_GUEST CPU flag mistakenly set as result.
