Zhongqiu Duan ce1a197169 tcp/dccp: allow a connection when sk_max_ack_backlog is zero 
[ Upstream commit 3479c7549fb1dfa7a1db4efb7347c7b8ef50de4b ]

If the backlog of listen() is set to zero, sk_acceptq_is_full() allows
one connection to be made, but inet_csk_reqsk_queue_is_full() does not.
When the net.ipv4.tcp_syncookies is zero, inet_csk_reqsk_queue_is_full()
will cause an immediate drop before the sk_acceptq_is_full() check in
tcp_conn_request(), resulting in no connection can be made.

This patch tries to keep consistent with 64a146513f ("[NET]: Revert
incorrect accept queue backlog changes.").
