netfilter: nf_ct_tcp: fix flow recovery with TCP window tracking enabled
This patch adds the missing bits to support the recovery of TCP flows without disabling window tracking (aka be_liberal). To ensure a successful recovery, we have to inject the window scale factor via ctnetlink. This patch has been tested with a development snapshot of conntrackd and the new clause `TCPWindowTracking' that allows to perform strict TCP window tracking recovery across fail-overs. With this patch, we don't update the receiver's window until it's not initiated. We require this to perform a successful recovery. Jozsef confirmed in a private email that this spotted a real issue since that should not happen.
