batman-adv: protect tt_local_entry from concurrent delete events
[ Upstream commit ef72706a0543d0c3a5ab29bd6378fdfb368118d9 ]
The tt_local_entry deletion performed in batadv_tt_local_remove() was neither
protecting against simultaneous deletes nor checking whether the element was
still part of the list before calling hlist_del_rcu().
Replacing the hlist_del_rcu() call with batadv_hash_remove() provides adequate
protection via hash spinlocks as well as an is-element-still-in-hash check to
avoid 'blind' hash removal.
