[dpdk-dev] [PATCH v4 13/14] test_memzone:fix finding the second smallest segment

[Chao Zhu <chaozhu@linux.vnet.ibm.com>]

Curent implementation in test_memzone.c has bugs in finding the
second smallest memory segment. It's the last smallest memory segment,
but it's not the second smallest memory segment. This bug may cause test
failure in some cases. This patch fixes this bug.
