[PATCH v2 1/3] app/testpmd: fix random value to set tunnel TSO

[Huisong Li <lihuisong@huawei.com>]

Currently, testpmd set tunnel TSO offload even if fail to get dev_info.
In this case, the 'tx_offload_capa' in dev_info is a random value,

Fixes: 6f51deb903b2 ("app/testpmd: check status of getting ethdev info")
