  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'.

Fixes: f1debd77efaf ("net/af_xdp: introduce AF_XDP PMD")
Fixes: 288a85aef192 ("net/af_xdp: enable custom XDP program loading")
