tcg_s390_tod_updated() is always called with the iothread being locked (e.g. from S390TODClass->set() e.g. via HELPER(sck) or on incoming migration). The helper we call takes the lock itself - bad. Let's change that by factoring out updating the ckc timer. This now looks much nicer than having to call a helper from another function. While touching it we also make sure that env->ckc is updated even if the new value is -1ULL, for now it would not have been modified in that case.
