[PATCH batadv v3 0/7] batman-adv: follow up fixes

While reviewing the fixes submitted to batman-adv in the recent weeks,
further problems in similar or adjecent code was identified. This was either
noticed in the manual review or reported by sashiko.dev.

Especially in the TT code, you have the global and the local translation
table. But when a bug was fixed, often only one of the two codepaths was
fixed. It was now tried to sync the TVLV preparation code between to of
them - not style wise but fixes wise. Besides the hardening, it will also
make the code less confusing.

The BLA and TP fixes are just some reference counting fixes - either
reference leak fixes or missing reference handling.
