[PATCH] conntrack event missing TCP protoinfo

[Rui Sousa <rui.p.m.sousa@gmail.com>]

Hi all,

Under some conditions it's possible to send a conntrack netlink event to 
userspace which is missing the TCP connection state 
(CDA_PROTOINFO_TCP_STATE) even though it is well defined.
This one liner should fix the problem. What do you think?

Br,
Rui
