Tetsuo Handa d337537181 smackfs: use netlbl_cfg_cipsov4_del() for deleting cipso_v4_doi ... [ Upstream commit 0934ad42bb2c5df90a1b9de690f93de735b622fe ] syzbot is reporting UAF at cipso_v4_doi_search() [1], for smk_cipso_doi() is calling kfree() without removing from the cipso_v4_doi_list list after netlbl_cfg_cipsov4_map_add() returned an error. We need to use netlbl_cfg_cipsov4_del() in order to remove from the list and wait for RCU grace period before kfree().
