Jisheng Zhang e9da4d6ac6 x86/idle: Restore trace_cpu_idle to mwait_idle() calls 
commit e43d0189ac upstream.

Commit b253149b84 ("sched/idle/x86: Restore mwait_idle() to fix boot
hangs, to improve power savings and to improve performance") restores
mwait_idle(), but the trace_cpu_idle related calls are missing. This
causes powertop on my old desktop powered by Intel Core2 E6550 to
report zero wakeups and zero events.

Add them back to restore the proper behaviour.

Fixes: b253149b84 ("sched/idle/x86: Restore mwait_idle() to ...")
