Tejun Heo 4e3cd8129c trace_events_filter: Use rcu_assign_pointer() when setting ftrace_event_call->filter ...

commit d3d9acf646 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.
