Subject: [PATCH net 3/5] batman-adv: Fix double-put of vlan object

From: Ben Hutchings <ben@...adent.org.uk>

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")
