Harmless in practice, because qdev_device_add() then fails, throwing
away @zpci. Fix it anyway.

Hi Markus,
Am I missing something here (a preceding patch maybe?) --
visit_type_uint32 is a void function. A quick look, no other callers
are checking it for a return value either...
The error value might get set in visit_type_uintN though. Taking a hint
from other places that handle this sort of case (ex:
cpu_max_set_sve_max_vq), maybe something like:
Error *err = NULL;
...
visit_type_uint32(v, name, ptr, &err);
if (err) {
error_propogate(errp, err);
return;
}
zpci->fid_defined = true;
Instead?
