  Docs: fix conntrack flow ct_state input

In the following envrionment:
  ovs-vsctl (Open vSwitch) 2.11.0
  DB Schema 7.16.1

we meet the following error during the tutorials
conntrack test:
  "ovs-ofctl: field +est missing value"
  "ovs-ofctl: field +trk missing value"
ovs-vsctl 2.9.0 has the same issue.

This patch gives the tutorials with right
conntrack input.
