[PATCH v2 29/44] qdev: Remove ArrayElementProperty.propname field

[Eduardo Habkost]

Now that we don't save the property name in Property.name
anymore, we don't need the to keep the property name string alive
after the property was registered.

We can remove the ArrayElementProperty.propname field, and free
the string immediately after registering the property.
