[PATCH RFC 09/11] Adopt rcu_read_lock() to lock monitor

[Hitoshi Mitake]

rcu_read_lock() issues lock_acquire() and rcu_read_unlock() issues lock_release().
They don't lock actual locks like spinlock or mutex.

So I replaced these calling of lock_acquire() and lock_release() with
lockdep_acquire() and lockdep_release().
