      Fix an RCU warning in the reading of user keys:
      
      ===================================================
      [ INFO: suspicious rcu_dereference_check() usage. ]
      ---------------------------------------------------
      security/keys/user_defined.c:202 invoked rcu_dereference_check() without protection!
      
      other info that might help us debug this:
      
      rcu_scheduler_active = 1, debug_locks = 0
      1 lock held by keyctl/3637:
       #0:  (&key->sem){+++++.}, at: [<ffffffff811a80ae>] keyctl_read_key+0x9c/0xcf
      
      stack backtrace:
