batman-adv: Fix double-put of vlan object
Each batadv_tt_local_entry hold a single reference to a
batadv_softif_vlan. In case a new entry cannot be added to the hash
table, the error path puts the reference, but the reference will also
now be dropped by batadv_tt_local_entry_release().
Fixes: a33d970d0b54 ("batman-adv: Fix reference counting of vlan object for tt_local_entry")
