Pablo Neira Ayuso 3db7e93d33 netfilter: ecache: always set events bits, filter them later
For the following rule:

iptables -I PREROUTING -t raw -j CT --ctevents assured

The event delivered looks like the following:

 [UPDATE] tcp      6 src=192.168.0.2 dst=192.168.1.2 sport=37041 dport=80 src=192.168.1.2 dst=192.168.1.100 sport=80 dport=37041 [ASSURED]

Note that the TCP protocol state is not included. For that reason
the CT event filtering is not very useful for conntrackd.

To resolve this issue, instead of conditionally setting the CT events
bits based on the ctmask, we always set them and perform the filtering
in the late stage, just before the delivery.

Thus, the event delivered looks like the following:

 [UPDATE] tcp      6 432000 ESTABLISHED src=192.168.0.2 dst=192.168.1.2 sport=37041 dport=80 src=192.168.1.2 dst=192.168.1.100 sport=80 dport=37041 [ASSURED]
