Eugene Grosbein c424a4201d net/tcpshow: fix parsing TSO-enabled "cooked" capture
Modern tcpdump may issue zero for octets encoding length of IP datagramm
that contains TCP packet captured with TCP Segmentation Offload enabled.
tcpshow breaks due to signed underflow in such case.
Fix it by using total length of captured packet from "length:" field
instead of zero value from packet data.
