tracing: Fix use-after-free in hist_unreg_all/hist_enable_unreg_all ...
While running tools/testing/selftests test suite with KASAN, Dmitry
Vyukov hit the following use-after-free report:
==================================================================
BUG: KASAN: use-after-free in hist_unreg_all+0x1a1/0x1d0 at addr
ffff880031632cc0
Read of size 8 by task ftracetest/7413
==================================================================
BUG kmalloc-128 (Not tainted): kasan: bad access detected
------------------------------------------------------------------
This fixes the problem, along with the same problem in
hist_enable_unreg_all().
