regulatory: clean up regdom_intersect
As the dummy_rule (also renamed from irule) is only used for output by the reg_rules_intersect() function there's no need to clear it at all, remove that. Acked-by: Luis R. Rodriguez <mcgrof@do-not-panic.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
