net: sched: act_ife: always release ife action on init error
Action init API was changed to always take reference to action, even when
overwriting existing action. Substitute conditional action release, which
was executed only if action is newly created, with unconditional release in
tcf_ife_init() error handling code to prevent double free or memory leak in
case of overwrite.
Fixes: 4e8ddd7f1758 ("net: sched: don't release reference on action overwrite")
