exec: Set cpu_index only if it's not been explictly set
It keeps the legacy behavior for all users that doesn't care
about stable cpu_index value, but would allow boards that
would support device_add/device_del to set stable cpu_index
that won't depend on order in which cpus are created/destroyed.
While at that simplify cpu_get_free_index() as cpu_index
generated by USER_ONLY and softmmu variants is the same
since none of the users support cpu-remove so far, except
of not yet released spapr/x86 device_add/delr, which
will be altered by follow up patches to set stable
cpu_index manually.
