xen-netback: move NAPI add/remove calls
Originally netif_napi_add was in xenvif_init_queue and netif_napi_del was in xenvif_deinit_queue, while kthreads were handled in xenvif_connect and xenvif_disconnect. Move netif_napi_add and netif_napi_del to xenvif_connect and xenvif_disconnect so that they reside together with kthread operations.
