iso-tester: Make use of bthost_add_iso_hook destroy callback

This makes use of bthost_add_iso_hook to track when an ISO connection
has been disconnected and then set its handle to 0x0000 which is then
checked when the socket HUP to confirm the remote has properly
disconnected (e.g. received Disconnected Complete).
