[PATCH 11/12] hw/s390x/ccw: Remove S390CcwMachineClass::max_threads field

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

The S390CcwMachineClass::max_threads field was only used by the
s390-ccw-virtio-7.1 machine, which got removed. Remove it
as now unused, simplifying the s390_init_cpus() method.
