app/crypto-perf: check lcore job failure

[ upstream commit 5908e7e ]

Currently, there's no return status check from lcore's jobs.
In case of fail - crypto-perf tool returns success anyway.
This patch adds such a detection and returns proper status at the end.

Fixes: ce8af1a ("app/crypto-perf: wait for cores launched by app")
