Fix uninitialized memory bug
Have interested callers of find_inheritance_children set the
detached_exist value to false prior to calling it, so that that routine
only has to set it true in the rare cases where it is necessary. Don't
touch it otherwise.
Per buildfarm member thorntail (which reported a UBSan failure here).
