s390: uv: Fix sysfs max number of VCPUs reporting
commit e82080e1f456467cc185fe65ee69fe9f9bd0b576 upstream.
The number reported by the query is N-1 and I think people reading the
sysfs file would expect N instead. For users creating VMs there's no
actual difference because KVM's limit is currently below the UV's
limit.
