  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'
(e.g. socket_id,max_nb_queue_pairs).

Fixes: 9e6edea41805 ("cryptodev: add APIs to assist PMD initialisation")
