[dpdk-dev] [PATCH] examples/kni: unchecked return value

[Daniel Mrzyglod]

Fix issue reported by Coverity.
Coverity ID 30692

If the function returns an error value, the error value may be mistaken for
a normal value.

In kni_free_kni: Value returned from a function is not checked for errors
before being used

Fixes: b475eb0bc400 ("examples/kni: new parameters")
