nvme-rdma: fix crash due to incorrect cqe A crash happened due to injecting error test. When a CQE has incorrect command id due do an error injection, the host may find a request which is already freed. Dereferencing req->mr->rkey causes a crash in nvme_rdma_process_nvme_rsp because the mr is already freed. Add a check for the mr to fix it.
