cryptodev: fix memory leak during stats query

[PATCH] cryptodev: fix memory leak during stats query

Posted by zhenwei pi 2 years, 9 months ago

object_get_canonical_path already returns newly allocated memory, this
means no additional g_strdup required. Remove g_strdup to avoid memory
leak.

Fixes: Coverity CID 1508074
Fixes: f2b901098 ("cryptodev: Support query-stats QMP command")
