commit 4a519b83da16927fb98fd32b0f598e639d1f1859 upstream.
Since commit 54e22f265e87 ("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.
