[dpdk-dev] [PATCH 2/2] app/crypto-perf: fix memcpy source range

detect size was more than source address range.

Actually, the source address is wrong.
The fix should be:

-               rte_memcpy(&ut_paramz[i].ut_params, &testsuite_params,
+               rte_memcpy(&ut_paramz[i].ut_params, &unittest_params,

Thanks for reporting this issue.
