[dpdk-dev] [PATCH 3/5] net/hns3: fix unchecked function call

[Min Hu (Connor)]

In hns3 PMD, as the handler always return 0, the return value
of a function 'rte_kvargs_process' no need to be checked. But
the API definition has return value, so 'void' could be used
to ignore that.

Fixes: a124f9e9591b ("net/hns3: add runtime config to select IO burst function")
