### Apache SkyWalking Component
OAP server (apache/skywalking)
### What happened
I try to develop a plugin for rocketMQ，there is an error when i build the
file
/tmp/go-build612827965/b348/skywalking_delegator.go:46:10: cannot use nil as
ConsumeResult value in return statement
/tmp/go-build612827965/b348/skywalking_delegator.go:59:9: cannot use nil as
ConsumeResult value in return statement
/tmp/go-build612827965/b348/skywalking_delegator.go:80:13: cannot use nil as
ConsumeResult value in assignment
### What you expected to happen
The enhanced method is in the`pushconsumer.go`
`func (pc *pushConsumer) consumeInner(ctx context.Context, subMsgs
[]*primitive.MessageExt) (ConsumeResult, error)`
and `type ConsumeResult int` defined in the `consumer.go`，
so when FilterAndEdit -> EnhanceParameterNames,
MethodEnhance.ParameterInfo.DefaultValueAsString will be "nil" because it
cannot determine the real type of the custom type.
### How to reproduce
the enhanced file's default return value will result in a type error when
custom type is an integer
such as
```
{
PackagePath: "consumer",
At: instrument.NewMethodEnhance("*pushConsumer", "consumeInner",
instrument.WithArgsCount(2),
instrument.WithArgType(0, "context.Context"),
instrument.WithArgType(1, "[]*primitive.MessageExt"),
instrument.WithResultCount(2),
instrument.WithResultType(0, "ConsumeResult"),
instrument.WithResultType(1, "error")),
Interceptor: "ConsumeInnerInterceptor",
}
```
and the enhanced file like
```
if invocation.isContinue {
if invocation.returnValues[0] != nil {
*ret_0 = (invocation.returnValues[0]).(ConsumeResult)
} else {
*ret_0 = nil
}
}
```
