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: 0a50a5aad299 ("mempool/cnxk: add device probe/remove")
