Tetsuo Handa 9a7bc0c403 batman-adv: initialize "struct batadv_tvlv_tt_vlan_data"->reserved field 
commit 08c27f3322fec11950b8f1384aa0f3b11d028528 upstream.

KMSAN found uninitialized value at batadv_tt_prepare_tvlv_local_data()
[1], for commit ced72933a5 ("batman-adv: use CRC32C instead of CRC16
in TT code") inserted 'reserved' field into "struct batadv_tvlv_tt_data"
and commit 7ea7b4a142 ("batman-adv: make the TT CRC logic VLAN
specific") moved that field to "struct batadv_tvlv_tt_vlan_data" but left
that field uninitialized.
