AT_USING_SOCKET_SERVER 与 const 的冲突。解决#182引起的

[ztlchina]

最新版本（2022-11-16 19:28:24） 开启了宏定义AT_USING_SOCKET_SERVER 与 atclient 包里的 const struct at_socket_ops socket_ops; / AT device socket operations */
冲突了。

#182
解决了182. 引起了新的问题。

按下葫芦浮起瓢。。。

编译错误：
../../../components/net/at/at_socket/at_socket.c(771): error: cannot assign to non-static data member 'socket_ops' with const-qualified type 'const struct at_socket_ops *'

我直接把const去掉

[yangpengya]

直接把store_at_socket_temporary删了，没用
