9P: Add cancelled() to the transport functions.
RDMA needs to post a buffer for each incoming reply. Hence it needs to keep count of these and needs to be aware of whether a flushed request has received a reply or not. This patch adds the cancelled() callback to the transport modules. It is called when RFLUSH has been received and that the corresponding request will never receive a reply.
