There is no code to delete `api_ctx` in APISIX. I guess it is because the
client closed the request before we assign an `api_ctx`. Would you apply the
patch to check if the `api_ctx` is assigned?
```diff
diff --git apisix/init.lua apisix/init.lua

```
BTW, is this problem only happened in subrequest?
