fix: fix miss makezero bug

[alingse]

I was running github actions to run linter makezero for top github golang repos.

see issues alingse/go-linter-runner#1

and the github actions output https://github.com/alingse/go-linter-runner/actions/runs/9242652074/job/25425741161

the vhs , keyList , subInstances is easy to check that they are bugs and they need make the slice to zero length.

but the other lines has var in that linter reported, I don't know if they are some special usage, so I wasn't commit them.

	in := make([]reflect.Value, 5) // maybe should replace with  in := make([]reflect.Value, 0, 5)
	in = append(in, srv.Rcvr())
	in = append(in, reflect.ValueOf(invocation.MethodName()))
	in = append(in, reflect.ValueOf(invocation.GetAttachmentInterface(constant.ParamsTypeKey)))
	in = append(in, reflect.ValueOf(args))
	in = append(in, reflect.ValueOf(invocation.Attachments()))
