The check to know if an invalidation is needed (i.e. when the context changes) is done even if the context does not exist yet. This happens when first setting a key for ciphers and/or hmac operations. This commits adds a check in the _setkey functions to only check if an invalidation is needed when a context exists, as there is no need to perform this check otherwise.
