[PATCH tip/core/rcu 06/41] sparc/oprofile: Convert timer_stop() to use synchronize_rcu()

Now that synchronize_rcu() waits for preempt-disable regions of code
in addition to explicitly marked RCU read-side critical sections,
synchronize_rcu() can be used in place of synchronize_sched().  This
commit therefore makes that change.
