oprofile: Remove deprecated use of flush_scheduled_work()
flush_scheduled_work() is deprecated and scheduled to be removed.
sync_stop() currently cancels cpu_buffer works inside buffer_mutex and
flushes the system workqueue outside. Instead, split end_cpu_work()
into two parts - stopping further work enqueues and flushing works -
and do the former inside buffer_mutex and latter outside.
For stable kernels v2.6.35.y and v2.6.36.y.
