crypto: algapi - remove obsoleted instance creation helpers
Remove lots of helper functions that were previously used for instantiating crypto templates, but are now unused: - crypto_get_attr_alg() and similar functions looked up an inner algorithm directly from a template parameter. These were replaced with getting the algorithm's name, then calling crypto_grab_*(). - crypto_init_spawn2() and similar functions initialized a spawn, given an algorithm. Similarly, these were replaced with crypto_grab_*(). - crypto_alloc_instance() and similar functions allocated an instance with a single spawn, given the inner algorithm. These aren't useful anymore since crypto_grab_*() need the instance allocated first. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
