Bluetooth: 6lowpan: always check destination address
BLE based 6LoWPAN networks are highly constrained in bandwidth.
Do not take a short-cut, always check if the destination address is
known to belong to a peer.
As a side-effect this also removes any behavioral differences between
one, and two or more connected peers.
