The above nvmet cm event handler, nvmet_rdma_cm_handler(), calls
nvmet_rdma_queue_connect() for CONNECT_REQUEST events, which calls
nvmet_rdma_alloc_queue (), which, if it encounters a failure (like creating
the qp), calls nvmet_rdma_cm_reject () which calls rdma_reject(). The
non-zero error, however, gets returned back here and this function returns
the error to the RDMA_CM which will also reject the connection as well as
destroy the cm_id. So there are two rejects happening, I think. Either
nvmet should reject and destroy the cm_id, or it should do neither and
return non-zero to the RDMA_CM to reject/destroy.
