i386: keep hyperv_vendor string up-to-date
When cpu->hyperv_vendor is not set manually we default to "Microsoft Hv" and in 'hv_passthrough' mode we get the information from the host. This information is stored in cpu->hyperv_vendor_id[] array but we don't update cpu->hyperv_vendor string so e.g. QMP's query-cpu-model-expansion output is incorrect.
