netdevsim: add NAPI support
Add NAPI support to netdevim, similar to veth.
* Add a nsim_rq rx queue structure to hold a NAPI instance and a skb
queue.
* During xmit, store the skb in the peer skb queue and schedule NAPI.
* During napi_poll(), drain the skb queue and pass up the stack.
* Add assoc between rxq and NAPI instance using netif_queue_set_napi().
