wmaker: fixed flag to avoid reloading config multiple times

The code includes a check whose goal is to avoid reloading more than once
the configuration, in case Inotify would report more than one change during
the event processing.

But the flag was not set so mechanism was ineffective, which is probably
ok anyway but as it is here let's make it work.
