sh: do not latency trace idle.
Description snipped from Steven Rostedt's PPC patch:
When idle is called, interrupts are blocked, but the idle
function will still wake up on an interrupt. The problem is
that the interrupt disabled latency tracer will take this call
to idle as a latency.
This patch disables the latency tracing when going into idle.
