batman-adv: Avoid storing non-TT-sync flags on singular entries too
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.
Fixes: 54e22f265e87 ("batman-adv: fix TT sync flag inconsistencies")
