[ovs-dev] [PATCH ovn 2/5] ovn-trace: Don't assert for next(stage=ingress, ..).

[numans at ovn.org]

From: Numan Siddique <numans at ovn.org>

The commit [1] allowed next action to advance from ingress to egress pipeline, but
ovn-trace was not modified to handle this condition. Also corrected the ovntrace node
format message as per the next stage.

[1] - b4b68177eb2f("Fix conntrack entry leaks because of TCP RST packets not sent to conntrack.")

Fixes: b4b68177eb2f("Fix conntrack entry leaks because of TCP RST packets not sent to conntrack.")
