acl: fix stats-segment counters validation on acl update
The stats-segment validation/clear logic for acl counters was wrong, fix it. Also add the code to the unittests to cover that case, add a vat command to enable/disable counters, clean up the unnecessary endian conversion and remove the stray clib_warning() Change-Id: I421297a92e4aeb885c468c72a97cec25981df615 Type: fix Ticket: VPP-1744 Fixes: f995c7122ba0d024b17bc3232e8edd18d5e25088 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit 4c945dacb9ff9da731301feb26b1edb4ac00e8bd)
