conntrackd: fix parsing of expectation class, helper name and NAT
I forgot to modify the body of msg2exp to include the recently
committed support for the expectation class, helper name and NAT.
This patch fixes the problem.
Now in node-1 (primary), it shows:
proto=17 src=192.168.11.4 dst=192.168.10.5 sport=0 dport=5060 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.10.5 master-dst=192.168.11.4 sport=5060 dport=5060 PERMANENT class=0 helper=sip [active since 31s]
And it node-2 (secondary), it shows:
proto=17 src=192.168.11.4 dst=192.168.10.5 sport=0 dport=5060 mask-src=255.255.255.255 mask-dst=255.255.255.255 sport=0 dport=65535 master-src=192.168.10.5 master-dst=192.168.11.4 sport=5060 dport=5060 PERMANENT class=0 helper=sip [active since 180s]
This has been tested with the SIP conntrack helper.
