tracing/function-return-tracer: add a barrier to ensure return stack index is incremented in memory
Impact: fix possible race condition in ftrace function return tracer

is not immediately flushed in memory.
Thanks for Andi Kleen and Steven Rostedt for pointing out this issue
and give me this solution.
