[PATCH v2 12/44] net/ena: fix segment fault when parse devargs

[Chengwen Feng]

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: cc0c5d251928 ("net/ena: make Tx completion timeout configurable")
Fixes: 8a7a73f26cc9 ("net/ena: support large LLQ headers")
