[I] selective_channel SubDone::Run最后的message交换可能会有内存问题 (brpc)
corznoc opened a new issue, #3372:
URL: https://github.com/apache/brpc/issues/3372
**Describe the bug**
selective_channel.cpp:
<img width="1097" height="2425" alt="Image" src="https://github.com/user-attachments/assets/1ded39be-3399-4622-a5fe-dbf460d0956a" />

对于一些无反射的Message（RedisResponse）, GetRelection()会返回空指针。
看了下PopFree()方法，之前的版本response成员，会使用用户传下来的response，
从而不会触发message交换。
**To Reproduce**
CallMethod使用RedisRequest和RedisResponse时，由于触发该问题。
**Expected behavior**
会引用空指针，触发SIGSEGV，反生coredump
**Versions**
OS: CentOS
Compiler: gcc
brpc: 1.17.0
protobuf: 3.25.8
**Additional context/screenshots**
