selinux: process labeled IPsec TCP SYN-ACK packets properly in selinux_ip_postroute()

commit c0828e50485932b7e019df377a6b0a8d1ebd3080 upstream.

Due to difficulty in arriving at the proper security label for
TCP SYN-ACK packets in selinux_ip_postroute(), we need to check packets
while/before they are undergoing XFRM transforms instead of waiting
until afterwards so that we can determine the correct security label.
