acl-plugin: do not do clib_smp_atomic_add on per-worker counters
Just do a regular increment, since we are not contending for these counters. This also makes the tests pass on ARM ThunderX (VPP-1395). Change-Id: I333aaa11d4145d13d322868900bc114df85a020d Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
