[dpdk-dev] [PATCH 08/14] net/hns3: fix memory leak with secondary process exit

[Lijun Ou]

the secondary process is applied a memory for the process_private
during initialization. Therefore, the memory needs to be released
when exiting.

Fixes: c203571b3602 ("net/hns3: register and add log interface")
