Title: Respond to DYNVC_CLOSE like described in MS-RDPEDYC 

Based on pull request #1475

When the DVC server manager initiates closing a channel, it sends a Close Request PDU that specifies the ChannelId to the DVC client manager. The client responds with a Close Response PDU that specifies the ChannelId.

The client response was missing.

fixes #1375
