VPP-95 VXLAN add_del API intermittent failure
The VXLAN add_del API sometimes rejects calls with
VNET_API_ERROR_SAME_SRC_DST when the two parameters are obviously
different. This is because the API code is checking the "is_ip6" flag in
a not-yet initialized area of memory leading to random results.
Also fix help text for vxlan_add_del_tunnel in vat.
This does not change the API; it repairs intermittent failure.
