Since commit 382d020fe3fa ("batman-adv: fix TT sync flag inconsistencies") TT sync flags and TT non-sync'd flags are supposed to be stored separately. The previous patch missed to apply this separation on a TT entry with only a single TT orig entry. This is a minor fix because with only a single TT orig entry the DDoS issue the former patch solves does not apply.
