Fix race in config entry setup

[bdraco]

Proposed change

If the config entry was reloaded while we are waiting for the lock to do the setup retry we should bail out since the config entry is already loaded. This was much more likely to happen if the event loop was blocked during startup.

It may have been possible for it to also happen the other way around where the event loop is blocked for a bit and the reload happens before the config entries are setup. This change will fix it for both paths since we check the state after getting the lock.
