[PATCH 1/2] examples/l3fwd: fix crash in ACL mode for mixed traffic

[Konstantin Ananyev <konstantin.v.ananyev@yandex.ru>]

From: Konstantin Ananyev <konstantin.ananyev@huawei.com>

When running l3fwd in ACL mode, if we'll have mix of IPv4/IPv6 packets in
the same burst, it will most likely cause a crash.
The reason for that is that we split our burst of packets into 2 arrays -
one for ipv4, another for ipv6 for classify().
But then we try to send all packets as one burst again, not taking into account
that acl_search.res_ipv4[] will be set only for ipv4 packets.
Same story for ipv6.
The fix is straightforward: use two already split arrays for TX.
