kni: fix deadlock in netif_receive_skb

Per netif_receive_skb function description, it may only be called from
interrupt contex, but KNI is run on kthread that like as user-space
context. It may occur deadlock, if netif_receive_skb called from kthread,
so it should be repleaced by netif_rx or adding local_bh_disable/enable
around netif_receive_skb.
