protoc gen adds comment, does not follow godoc. about grpc-go

[purnesh42H]

@titpetric we can fix this by adding punctuation in protoc generation here https://github.com/grpc/grpc-go/blob/master/cmd/protoc-gen-go-grpc/grpc.go#L267 and then regenerate all pb.go files. Do you want to give a try for fix?
