crypto: talitos - fix hashing

BugLink: http://bugs.launchpad.net/bugs/1721777
commit 886a27c0fc8a34633aadb0986dba11d8c150ae2e upstream.

md5sum on some files gives wrong result

Exemple:

With the md5sum from libkcapi:
c15115c05bad51113f81bdaee735dd09  test

With the original md5sum:
bbdf41d80ba7e8b2b7be3a0772be76cb  test

This patch fixes this issue
