Subject: [PATCH] Bluetooth: 6lowpan: Fix lockdep splats

When a device ndo_start_xmit() calls again dev_queue_xmit(),
lockdep can complain because dev_queue_xmit() is re-entered and the
spinlocks protecting tx queues share a common lockdep class.

Same issue was fixed for ieee802154 in commit "20e7c4e80dcd"
