    Bug-fix: first dequeue lock entry from queue, then perform op in this entry · a44c53d6

    Here we should first dequeue the current lock queue entry from
    lock queue then performing the operation in it. This is because
    when performing op in current lock entry, we may trigger
    release_lock() function, which go to check the lock queue again.
    If we did not remove current entry from the queue, release_lock()
    will try to process it for the second time, which leads to the wrong
    execution.
