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'.
If the input args is just "name" (which mean only has keys), then it
will get (null) name in rte_cryptodev_pmd_parse_name_arg(). This patch
fixes it.
