[dpdk-dev] [PATCH v2 2/2] app/crypto-perf: fix memcpy source

Since arm64 was using plain memcpy for rte_memcpy, gcc 8.1, could
detect size was more than source address range. In this case, the
source was wrong.

/export/dpdk.org/test/test/test_cryptodev.c: In function
'test_multi_session_random_usage':
/export/dpdk.org/build/include/rte_memcpy_64.h:364:29: error: 'memcpy'
forming offset [113, 184] is out of the bounds [0, 112] of object
'testsuite_params' with type 'struct crypto_testsuite_params'
[-Werror=array-bounds]
 #define rte_memcpy(d, s, n) memcpy((d), (s), (n))
                             ^~~~~~~~~~~~~~~~~~~~~
/export/dpdk.org/test/test/test_cryptodev.c:6618:3: note: in expansion
of macro 'rte_memcpy'
   rte_memcpy(&ut_paramz[i].ut_params, &testsuite_params,
   ^~~~~~~~~~
/export/dpdk.org/test/test/test_cryptodev.c:140:39: note:
'testsuite_params' declared here
 static struct crypto_testsuite_params testsuite_params = { NULL };
