perf, x86: P4_pmu_schedule_events -- use smp_processor_id instead of raw_

This snippet somehow escaped the commit:

 | commit 137351e0feeb9f25d99488ee1afc1c79f5499a9a
 | Author: Cyrill Gorcunov <gorcunov@openvz.org>

 |    x86, perf: P4 PMU -- protect sensible procedures from preemption

so bring it eventually back. It helps to catch
preemption issue (if there will be, rule of thumb --
don't use raw_ if you can).
