rcu: Remove lockdep annotations from RCU's _notrace() API members

The lockdep annotations rcu_read_acquire() and rcu_read_release()
might lead to infinite looping if called from lockdep.  So this patch
removes them.  Formal repost of http://lkml.org/lkml/2009/8/25/309
on the strength of Lai Jiangshan's review.
