Currently, based on config_direct_link variable, link is voted up or down which can result in same multiple votes. To fix this, vote link up or down if there is a change in previous config and incoming config_direct_link argument. Also, return status success when direct link is not enabled but dp_config_direct_link is called. Change-Id: I4f54d74a9d4921f27f247450f89a03d6dabc838e CRs-Fixed: 3375395
