During the startup process we don't have any fdtab nor fd_updt for quite a long time, and as such some operations on the listeners are not permitted, such as fd_want_*/fd_stop_* or fd_delete(). The latter is of particular concern because it's used when stopping a disabled frontend, and it's performed very early during check_config_validity() while there is no fdtab yet. The trick till now relies on the listener's state which is a bit brittle. There is absolutely no valid reason for stopping a proxy's listeners this early, we can postpone it after init_pollers() which will at least have allocated fdtab.
