net/sched: act_gate: snapshot parameters with RCU on replace
commit 62413a9c3cb183afb9bb6e94dd68caf4e4145f4c upstream.
The gate action can be replaced while the hrtimer callback or dump path is
walking the schedule list.
Convert the parameters to an RCU-protected snapshot and swap updates under
tcf_lock, freeing the previous snapshot via call_rcu(). When REPLACE omits
the entry list, preserve the existing schedule so the effective state is
unchanged.
