[ Upstream commit 0e7d4d932ffc23f75efb31a8c2ac2396c1b81c55 ]

This patch fixes two typos related to unregistering algorithms supported by
SAHARAH 3. In sahara_register_algs the wrong algorithms are unregistered
in case of an error. In sahara_unregister_algs the wrong array is used to
determine the iteration count.
