[PATCH tip/core/rcu 17/41] fs/file: Replace synchronize_sched() with synchronize_rcu()

Paul E. McKenney

Now that synchronize_rcu() waits for preempt-disable regions of code
as well as RCU read-side critical sections, synchronize_sched() can be
replaced by synchronize_rcu(). This commit therefore makes this change.
