Convert the "seqiv" template to the new way of freeing instances where a ->free() method is installed to the instance struct itself. Also remove the unused implementation of the old way of freeing instances from the "echainiv" template, since it's already using the new way too. In doing this, also simplify the code by making the helper function aead_geniv_alloc() install the ->free() method, instead of making seqiv and echainiv do this themselves. This is analogous to how skcipher_alloc_instance_simple() works. This will allow removing support for the old way of freeing instances.
