batman-adv: Check for alloc errors when preparing TT local data
batadv_tt_prepare_tvlv_local_data can fail to allocate the memory for the
new TVLV block. The caller is informed about this problem with the returned
length of 0. Not checking this value results in an invalid memory access
when either tt_data or tt_change is accessed.

Fixes: 7ea7b4a14275 ("batman-adv: make the TT CRC logic VLAN specific")
