Subject: [PATCH net 5/6] selftests: mptcp: fix case multiple subflows limited by server

From: Jianguo Wu <wujianguo@...natelecom.cn>

After patch "mptcp: fix syncookie process if mptcp can not_accept new
subflow", if subflow is limited, MP_JOIN SYN is dropped, and no SYN/ACK
will be replied.

So in case "multiple subflows limited by server", the expected SYN/ACK
number should be 1.

Fixes: 00587187ad30 ("selftests: mptcp: add test cases for mptcp join tests with syn cookies")
