batman-adv: tp_meter: simplify unordered ack calculation

Browse Source 
When batadv_tp_ack_unordered() goes through the list of unacked sequence
numbers and checks for now closed gaps, it is first calculating a delta of
the sequence numbers which could be acked. Just to revert this calculation
in the next steps to the sequence number which would be ackable.

Skip the delta step and directly work with the sequence numbers.
