KVM: s390: handle machine checks when guest is running
The low-level interrupt handler on s390 checks for _TIF_WORK_INT and
exits the guest context, if work is pending.
TIF_WORK_INT is defined as_TIF_SIGPENDING | _TIF_NEED_RESCHED |
_TIF_MCCK_PENDING. Currently the sie loop checks for signals and
reschedule, but it does not check for machine checks. That means that
we exit the guest context if a machine check is pending, but we do not
handle the machine check.
