AsynMultiInterestUserProcessor在执行时被当做SyncUserProcessor

[adisby]

Describe the bug
由于AsynMultiInterestUserProcessor不是AsyncUserProcessor的子类，所以在RpcRequestProcessor.dispatchToUserProcessor()方法中被当做了SyncUserProcessor执行并同步等待，最终抛出异常

https://github.com/alipay/sofa-bolt/blob/531d1c0d872553d92fc55775565b3f7be8661afa/src/main/java/com/alipay/remoting/rpc/protocol/RpcRequestProcessor.java#L222

Expected behavior

AsynMultiInterestUserProcessor所注册的业务会异步处理

Actual behavior

AsynMultiInterestUserProcessor所注册的业务被当做SyncUserProcessor并且执行时抛出异常

Steps to reproduce

Minimal yet complete reproducer code (or GitHub URL to code)

I can replay it.
when I define a UserProcessor class
public class SimpleAsynMultiInterestUserProcessor extends AsynMultiInterestUserProcessor

when client call the server,the client side get the error stack:
com.alipay.remoting.rpc.exception.InvokeServerException: Server exception! Please check the server log, the address is 127.0.0.1:8999, id=1, ServerErrorMsg:null
