Yuchung Cheng ecde8f36f8 tcp: fix lost retransmit SNMP under-counting 
The lost retransmit SNMP stat is under-counting retransmission
that uses segment offloading. This patch fixes that so all
retransmission related SNMP counters are consistent.

Fixes: 10d3be5692 ("tcp-tso: do not split TSO packets at retransmit time")
