In memif_socket_init(), when rte_hash_add_key_data() fails, clean up the newly created socket including unregistering callback, closing fd and freeing intr_handle for listener sockets. In memif_socket_remove_device(), unregister the listener callback and close the socket fd before freeing the interrupt handle.
