Subject: [PATCH] net: sctp: sctp_setsockopt_auth_key: use kzfree instead of
 kfree

[ Upstream commit 6ba542a291a5e558603ac51cda9bded347ce7627 ]

In sctp_setsockopt_auth_key, we create a temporary copy of the user
passed shared auth key for the endpoint or association and after
internal setup, we free it right away. Since it's sensitive data, we
should zero out the key before returning the memory back to the
allocator. Thus, use kzfree instead of kfree, just as we do in
sctp_auth_key_put().
