  This patch tries to fix the coverity issue of unchecked
return value. Since the function that causes the problem
is unused, it is removed completely.

Coverity issue: 336816
Fixes: f5188211c721 ("examples/vhost_crypto: add sample application")
Cc: stable@dpdk.org

Hi Jens,

You are right. Sorry the code wasn't cleaned up properly in the first place.
Do you want me to send a v2 with new title?

Regards,
Fan
