If reconnect/reset failed where the controller async event buffer was freed, we might end up freeing it again as we call nvme_rdma_destroy_admin_queue again in the remove path. Given that the sequence is guaranteed to serialize by .ctrl_stop, we simply set ctrl->async_event_sqe.data to NULL and don't free it in future visits.
