fix: raise error in peek() function of linkedlist_stack.py, linkedlist_queue.py, linkedlist_deque.py (#754) ...

* fix: linkedlist_stack.py 中的peek方法需要判空raise Error

栈空的时候不能再 peek() 。另外由于 pop() 复用了 peek() ，栈空时返回的 None 会传递到 pop() 中的 num ，导致后续的继续执行 
 self.peek.next 报错等后续问题

* Update linkedlist_stack.py

* Update linkedlist_queue.py

* Update linkedlist_deque.py
