sprintf function is not secure as it doesn't check the length of string.
More secure function snprintf is used.
Fixes: 473d1bebce ("hash: allow to store data in hash table")

Sorry for the late reply, but I noticed the test folder is recently moved under app so you may need a rebase.
Please keep my ack after rebase: Acked-by: Yipeng Wang <yipeng1.wang at intel.com>
