[PATCH v2] net/iavf: fix error devargs parsing

[Mingjin Ye]

This patch fixes unknown parsing results in the absence of
devarg "no-poll-on-link-down" and fixes the devarg variable type.

Fixes: 5b3124a0a6ef ("net/iavf: support no polling when link down")
Fixes: 3e6a5d2d310a ("net/iavf: add devargs to enable VF auto-reset")
Cc: stable at dpdk.org
