[dpdk-dev] [PATCH v2 2/7] net/hinic/base: fix hotupdate firmware problem

[Xiaoyun wang]

When repeatedly hotupdate firmware and start/stop port at the same time,
port start may be failed when cmdq reinit failed at the fw active phase,
so if deteted status of cmdq is fail, then reinit the cmdq when port start.

Fixes: d9ce1917941c ("net/hinic/base: add hardware operation")
