Subject: [PATCH 05/17] batman-adv: Remove unnecessary lockdep in batadv_mcast_mla_list_free

From: Linus Lüssing <linus.luessing@...3.blue>

batadv_mcast_mla_list_free() just frees some leftovers of a local feast
in batadv_mcast_mla_update(). No lockdep needed as it has nothing to do
with bat_priv->mcast.mla_list.
