batman-adv: fix for leaked TVLV handler.

Browse Source 
[ Upstream commit 17f78dd1bd624a4dd78ed5db3284a63ee807fcc3 ]

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")
