trace_events_filter: Use rcu_assign_pointer() when setting ftrace_event_call->filter
commit d3d9acf646679c1981032b0985b386d12fccc60c upstream.
ftrace_event_call->filter is sched RCU protected but didn't use
rcu_assign_pointer(). Use it.
TODO: Add proper __rcu annotation to call->filter and all its users.
-v2: Use RCU_INIT_POINTER() for %NULL clearing as suggested by Eric.
