batman-adv: Fix broadcast duplist for fragmentation
If the skb is fragmented, the checksum must be computed on the individual fragments, just using skb->data may fail on fragmented data. Instead of doing linearizing the packet, use the new batadv_crc32 to do that more efficiently- it should not hurt replacing the old crc16 by the new crc32.
