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.
Fixes: 122edaa05940 ("batman-adv: tvlv - convert roaming adv packet to use tvlv unicast packets")
