Release all connected streams when routing device is changed.

When there is a routing change, the existing mmap endpoint is
invalidated and can no longer be used. In that case, release all
registered streams and set the endpoint as disconnected so that it won't
be reused by another new request. That also releases the resources from
the service side so that it won't be harmful if the clients don't close
the stream when receiving disconnect event.
