So to on safe side, instead of having custom wrapper to do numbering replace it with cpu_generic_init() and use S390CPUClass::next_cpu_id which could serve the same purpose as static variable and move cpu->id initialization to s390_cpu_initfn for CONFIG_USER_ONLY use-case. PS: ifdef is ugly but it allows us to hide s390x detail that isn't set by *-user targets and reuse generic cpu creation utility for btoh machine and user emulation.
