crypto: api - Change crypto_unregister_instance argument type
This patch makes crypto_unregister_instance take a crypto_instance instead of a crypto_alg. This allows us to remove a duplicate CRYPTO_ALG_INSTANCE check in crypto_unregister_instance. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
