[PATCH 19/22] target/s390x: Have s390_realize_cpu_model() return a boolean

[Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>]

Following the example documented since commit e3fe3988d7 ("error:
Document Error API usage rules"), have s390_realize_cpu_model()
return a boolean indicating whether an error is set or not.
