It's a false positive.
After nbd_client_new calls nbd_send_negotiate, either it returns or
client escapes via QTAILQ_INSERT_TAIL (either in nbd_client_new or in
nbd_handle_export_name).
So I think it's the same as below.

It seems okay to me too, but these are exactly the false positive that
the g_malloc model is supposed to avoid...
