crypto: api - Do not zap spawn->alg
Currently when a spawn is removed we will zap its alg field. This is racy because the spawn could belong to an unregistered instance which may dereference the spawn->alg field. This patch fixes this by keeping spawn->alg constant and instead adding a new spawn->dead field to indicate that a spawn is going away. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
