anv: properly store the engine_class_supported_count values

Function anv_physical_device_try_create() creates the devinfo variable
and then at some point it copies its contents to device->info:

  device->info = devinfo;

Much much later we're calling:

  intel_common_update_device_info(fd, &devinfo);

... which is updating devinfo but not device->info. As a consequence,
we're only creating one queue, as engine_class_supported_count[klass]
is zero for everybody.
