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 5ff3fec6 ("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.
