[CRYPTO] api: Added spawns
Spawns lock a specific crypto algorithm in place. They can then be used with crypto_spawn_tfm to allocate a tfm for that algorithm. When the base algorithm of a spawn is deregistered, all its spawns will be automatically removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
