'colo_mark_tcp_pkt' should return 'true' when packets are the same, and
'false' otherwise. However, it returns 'true' when
'colo_compare_packet_payload' returns non-zero while
'colo_compare_packet_payload' is just a 'memcmp'. The result is that
COLO-compare reports inconsistent TCP packets when they are actually
the same.
Fixes: f449c9e549c ("colo: compare the packet based on the tcp sequence number")
