If cma_acquire_dev_by_src_ip() returns error in addr_handler(), the device state changes back to RDMA_CM_ADDR_BOUND but the resolved source IP address is still left. After that, if rdma_destroy_id() is called after rdma_listen(), the device is freed without removed from listen_any_list in cma_cancel_operation(). Revert to the previous IP address if acquiring device fails.
