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.
Fixes: c929500d7a5a ("s390/nmi: s390: New low level handling for machine check happening in guest")
