[TCP]: Fix GSO ignorance of pkts_acked arg (cong.cntrl modules) The code used to ignore GSO completely, passing either way too small or zero pkts_acked when GSO skb or part of it got ACKed. In addition, there is no need to calculate the value in the loop but simple arithmetics after the loop is sufficient. There is no need to handle SYN case specially because congestion control modules are not yet initialized when FLAG_SYN_ACKED is set.
