[dpdk-dev] [v4]net/hinic: fix coredump when the scondary process using the hinic port.

[Wangxiaoyun (Cloud)]

Hi Ferruh,

Align with Qingqing Li, this path will not apply to dpdk master now, some dev_ops may
casue fail when run in secondary proc, so need to modify it later and add tests for other
dev_ops.

Thanks
