crypto: api - Add crypto_alloc_instance2
This patch adds a new argument to crypto_alloc_instance which sets aside some space before the instance for use by algorithms such as shash that place type-specific data before crypto_alg. For compatibility the function has been renamed so that existing users aren't affected. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
