  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: 8d1d9070bbe9 ("event/dlb2: optimize producer port probing")
Fixes: bec8901bfe9f ("event/dlb2: support ldb port specific COS")
