[PATCH RFC batadv v4 8/8] batman-adv: tt: decrement count for committed client on local_remove

Local TT entries which have the BATADV_TT_CLIENT_NEW no longer set are
committed. The batadv_tt_local_size_inc() was called for them and thus the
batadv_tt_local_size_dec() has to be called also when
batadv_tt_local_remove() is called for them when the BATADV_TT_CLIENT_NEW
wasn't consumed in the remove path.
