[ Upstream commit 2d94b20b95b009eec1a267dcf026b01af627c0cd ]
Since commit 656c8e9cc1ba ("netfilter: conntrack: Use consistent ct id
hash calculation") the ct id will not change from initialization to
confirmation. Removing the confirmation check allows for things like
adding an element to a 'typeof ct id' set in prerouting upon reception
of the first packet of a new connection, and then being able to
reference that set consistently both before and after the connection
is confirmed.
Fixes: 656c8e9cc1ba ("netfilter: conntrack: Use consistent ct id hash calculation")
