In tcp_hdr_options test, it ensures the received tcp hdr option and the sk local storage have the expected values. It uses memcmp to check that. Testing the memcmp result with ASSERT_OK is confusing because ASSERT_OK will print out the errno which is not set. This patch uses ASSERT_EQ to check for 0 instead.
