batman-adv: tp_meter: handle overlapping packets

If the size of the packets would change during the transmission, it could
happen that some retries of packets are overlapping. In this case, precise
comparisons of sequence numbers by the receiver would be wrong. It is then
necessary to check if the start sequence number to the end sequence number
("seqno + length") would contain a new range.

If this is the case then this is enough to accept this packet. In all other
cases, the packet still has to be dropped (and not acked).
