accel-cpu: make cpu_realizefn return a bool

Browse source 
overall, all devices' realize functions take an Error **errp, but return void.

hw/core/qdev.c code, which realizes devices, therefore does:

local_err = NULL;
dc->realize(dev, &local_err);
if (local_err != NULL) {
    goto fail;
}

However, we can improve at least accel_cpu to return a meaningful bool value.
