[dpdk-dev] [PATCH] crypto: fix memory leak

[Pablo de Lara]

When parsing the parameters for virtual device initialization,
rte_kvargs structure was being freed only if there was an error,
not when parsing was successful.

Coverity issue: 124568

Fixes: f3e764fa2fb7 ("cryptodev: uninline parameter parsing")
