[PATCH 1/1] iproute2 actions: BugFix action stats to display with -s

[Jamal Hadi Salim <jhs@mojatatu.com>]

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

Was broken by commit 288abf513f5d11b98f09c6977d2019097afb7e9f
Lets not be too clever and have a separate call to print flushed
actions info.

Broken looks like:
root@moja-1:~# tc actions add  action drop index 4
root@moja-1:~# tc -s actions ls action gact

    action order 0: gact action drop
     random type none pass val 0
     index 4 ref 1 bind 0 installed 9 sec used 4 sec

The fixed version looks like:
    action order 0: gact action drop
     random type none pass val 0
     index 4 ref 1 bind 0 installed 9 sec used 4 sec
         Sent 108948 bytes 1297 pkts (dropped 1297, overlimits 0)
