Merge tag 'kvm-s390-master-5.8-3' of git://git./linux/kernel/git/kvms390/linux into kvm-master

The current number of KVM_IRQCHIP_NUM_PINS results in an order 3
allocation (32kb) for each guest start/restart which can result in OOM
killer activity when kernel memory is fragmented enough.

This fix reduces the number of iopins as s390 doesn't use them, hence
reducing the memory footprint.
