pf synproxy broken

[Yuriy N. Shkandybin]

Hello.

Please look at PR  86072.
I've confirm that this issue exist in latest STABLE and HEAD.

How it looks:
1) without synproxy
 telnet localhost 22
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
SSH-2.0-OpenSSH_4.2p1 FreeBSD-20050903

2) with synproxy
pass in log on lo0 proto tcp from any to any port 22 flags S/SA synproxy state
 telnet localhost 22
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.


That's all no actual connection.

netstat:
tcp4       0      0  127.0.0.1.45427        127.0.0.1.22           ESTABLISHED

pfсtl -s state
self tcp 127.0.0.1:22 <- 127.0.0.1:45427       PROXY:DST
