s390x: Migrate to new NMI interface
This implements an NMI interface for s390 and s390-ccw machines.
This removes #ifdef s390 branch in qmp_inject_nmi so new s390's
nmi_monitor_handler() callback is going to be used for NMI.
Since nmi_monitor_handler()-calling code is platform independent,
CPUState::cpu_index is used instead of S390CPU::env.cpu_num.
There should not be any change in behaviour as both @cpu_index and
@cpu_num are global CPU numbers.
Note that s390_cpu_restart() already takes care of the specified cpu,
so we don't need to schedule via async_run_on_cpu().
Since the only error s390_cpu_restart() can return is ENOSYS, convert
it to QERR_UNSUPPORTED.
