[PATCH v2 2/6] app/testpmd: fix burst option parsing

[David Marchand]

rte_eth_dev_info_get() is not supposed to fail for a valid port_id, but
for the theoretical case when it would fail, raise an error rather than
skip subsequent options.

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