commit 87445d81c360a5f9833546114e98ffd2c1fd3a4d Author: Jeremy Sowden jeremy@azazel.net Date: Tue May 21 20:58:57 2019 +0100

batman-adv: fix for leaked TVLV handler.

A handler for BATADV_TVLV_ROAM was being registered when the translation-table was initialized, but not unregistered when the translation-table was freed. Unregister it.
