Subject: [PATCH] app/crypto-perf: fix excess crypto device error

[ upstream commit dc476f122d9d80173a3b2b68870dc9f334f296c3 ]

If number of available devices are more than logical core,
there is no need to throw an error.
Just use the less number of devices instead.

Fixes: f8be1786b1b8 ("app/crypto-perf: introduce performance test application")
