**To Reproduce (复现方法)**
ChannelOptions:
```
brpc::ChannelOptions options;
options.backup_request_ms = FLAGS_backup_timeout_ms;
options.protocol = FLAGS_protocol;
options.connection_type = FLAGS_connection_type;
options.timeout_ms = 10000;
options.max_retry = 9999;
options.connect_timeout_ms = 5000;
```
Run client when there's no started server.
**Expected behavior (期望行为)**
No crash after reties.
**Versions (各种版本)**
OS:
Compiler:
brpc:
protobuf:
