[PATCH v6 08/20] gro: fix overwrite unprocessed packets

[Andre Muezerie <andremue@linux.microsoft.com>]

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

gro_vxlan_tcp4_tbl_timeout_flush() is called without taking into account
that first entries in pkts[] can be already occupied by
un-processed packets.

Fixes: 74080d7dcf31 ("gro: support IPv6 for TCP")
Cc: stable@dpdk.org
