[PATCH v2 18/44] net/idpf: fix segment fault when parse devargs

[Chengwen Feng]

The rte_kvargs_process() was used to parse KV pairs, it also supports
to parse 'only keys' (e.g. socket_id) type. And the callback function
parameter 'value' is NULL when parsed 'only keys'.

This patch fixes segment fault when parse input args with 'only keys'.
