Subject: [PATCH] tracing: Use sched_clock_cpu for trace_clock_global

For systems with an unstable sched_clock, all cpu_clock() does is enable/
disable local irq during the call to sched_clock_cpu().  And for stable
systems they are same.

trace_clock_global() already disables interrupts, so it can call
sched_clock_cpu() directly.
