[dpdk-dev] [PATCH 05/10] app/test: add null pointer check of memory allocation

[Min Hu (Connor)]

From: HongBo Zheng <zhenghong...@huawei.com>

The rte_zmalloc is called in test_crc_calc without null pointer
check. This patch adds null pointer checks on return value of
rte_zmalloc.

Fixes: 9c77b848b1c1 ("test: add CRC computation")
