For top-level qdev properties, this is always set and matches 'prop->name'. However, for list elements it is NULL, because each element of a list doesn't have a separate name. Passing a non-NULL value runs into assertion failures in the visitor code. Therefore, using 'name' in error messages is not right for property types that are used in lists, because "(null)" isn't very helpful to identify what QEMU is complaining about. Change netdev properties to use 'prop->name' instead, which will contain the name of the array property after switching array properties to lists in the external interface.
