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>
