bluetooth: 6lowpan: fix NOHZ: local_softirq_pending
Jukka reported about the following warning: "NOHZ: local_softirq_pending 08" I remember this warning and we had a similar issue when using workqueues and calling netif_rx. See commit 5ff3fec ("mac802154: fix NOHZ local_softirq_pending 08 warning"). This warning occurs when calling "netif_rx" inside the wrong context (non softirq context). The net core api offers "netif_rx_ni" to call netif_rx inside the correct softirq context.
