When an expected connection arrives, the NAT helper should be called to
set up NAT similar to the master connection. The PPTP conntrack helper
incorrectly checks whether the _expected_ connection has NAT setup before
calling the NAT helper (which is never the case), instead of checkeing
whether the _master_ connection is NATed.
