net: sctp: sctp_setsockopt_auth_key: use kzfree instead of kfree
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().
