[dpdk-stable] [PATCH] app/test-crypto-perf: fix crypto operation resubmission

[Fan Zhang]

This patch fixes the crypto operation resubmission problem in crypto
perferformance test. Originally, when needed crypto ops amount is
smaller than the enqueued crypto ops in the last round, one or more
processed crypto operations will be re-enqueued.

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