As part of start_ap or connect_start to teardown active tdls peers hdd_notify_teardown_tdls_links is called with argument vdev. But TDLS might not be enabled on that vdev. With recent changes, osif_priv object is initialized as part of tdls_vdev_init. For the new interface if TDLS is not initialized then osif_priv object will not be found and TDLS peers are not removed. Change-Id: Idcf690bba2766664700a4851d390ee620f2fe73a CRs-Fixed: 2460108
