[ Upstream commit a7da441621c7945fbfd43ed239c93b8073cda502 ]
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")
