> When setting a callback on a Glib source and giving it a data pointer,
> it's natural to also provide the destructor for the data in question.
> 
> Since migrate_hup_add() already needs to clone the MigrationAddress
> when setting the qmp_migrate_finish_cb callback, also pass the
> qapi_free_MigrationAddress as the GDestroyNotify callback.
> 
> With this the address doesn't need to be freed at the callback body,
> making the management of that memory slightly simpler.

>     closes the cpr state and deletes the HUP source itself (upstream had
