  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")

Why not just initialise this to zeros?

The main purpose of this function is to check which tunnel TSO offload 
port supports instead of getting dev_info, right?

Agree with Huisong, zeroing out the dev_info doesn't help much, this
function still will fail to do its job, and caller function will still
get wrong dev info.
