commit 8ac6fcae5dc0e801f1c82a83f5ae2c0a4db19932 upstream.
To handle device removal, svc_rdma_accept() requests removal notification for the underlying device when accepting a connection. However svc_rdma_free() is not invoked if svc_rdma_accept() fails. There needs to be a matching "unregister" in that case; otherwise the device cannot be removed.
