Subject: trace/latency-hist: Consider new argument when probing the
 sched_switch tracer
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.6/older/patches-4.6.2-rt5.tar.xz

The sched_switch tracer has got a new argument. Fix the latency tracer
accordingly.

Recently: c73464b1c843 ("sched/core: Fix trace_sched_switch()") since
v4.4-rc1.
