portio: keep references on portio
The isa_register_portio_list() function allocates ioports
data/state. Let's keep the reference to this data on some owner. This
isn't enough to fix leaks, but at least, ASAN stops complaining of
direct leaks. Further cleanup would require calling
portio_list_del/destroy().
