Commit3f1087cadded a per zone limit test which relied on the CHECK_CT_DPIF_FLUSH_BY_CT_TUPLE m4 macro to skip the test when executing in a userspace datapath (since the per zone limit feature is not yet implemented in userspace). That macro, however, has been removed in commit271e48a("conntrack: Support conntrack flush by ct 5-tuple") which was causing the test to fail when executing in userspace. Instead, a new m4 macro, CHECK_CT_DPIF_PER_ZONE_LIMIT, is introduced to make the same differentiation, until userspace doesn't support the per zone limit.
