Subject: [PATCH 1/1] actions: correctly report the number of actions flushed

From: Jamal Hadi Salim <jhs@...atatu.com>

This also fixes a long standing bug of not sanely reporting the
action chain ordering

Sample scenario test

on window 1(event window):
run "tc monitor" and observe events

on window 2:
sudo tc actions add action drop index 10
sudo tc actions add action ok index 12
sudo tc actions ls action gact
sudo tc actions flush action gact

See the event window reporting two entries
(doing another listing should show empty generic actions)
