The function lowpan_frag_rcv does return only:
- "1": skb is reassmbled
- "-1": skb is putted into the frag bucket or failure.
Other values can't happend. This patch will change that we return on "1"
the return value of netif_rx and "-1" to NET_RX_DROP, which means that
the packet doesn't reach the next layer.
