target-i386: Require APIC ID to be explicitly set before CPU realize
Instead of setting APIC ID automatically when creating a X86CPU, require the property to be set before realizing the object (which all callers of cpu_x86_create() already do). Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
