Description
at_delete_resp函数的resp=RT_NULL操作，无法置实参为RT_NULL
https://github.com/RT-Thread/rt-thread/blob/765c2ec5f92e82596e1edc2cab6b1a741fd1cc3e/components/net/at/src/at_client.c#L94
调用at样例中大多数这样使用：at_delete_resp(resp)
实参resp在调用后并未被置为RT_NULL
若后续使用resp变量会出问题。
目前只能在at_delete_resp(resp)后，再写一行resp=RT_NULL。

Research direction
Inspect at_delete_resp in components/net/at/src/at_client.c around line 94, then search the AT examples and other call sites that invoke it with resp. Determine how the API can ensure the caller's resp is cleared, and verify that subsequent use of the variable is safe across the affected call sites.
