rpc-transport/rdma: handle cases where peer is NULL in send_completion.v3.1.3qa8
- There can be valid cases where peer is NULL - For eg., race b/w pollin received on handshake socket and as a result transport getting disconnected and handling of a send/recv completion on the same qp for some previous read/write - in send/recv_completion_process. Hence we should be checking for a valid peer pointer before accessing it.
