Remove request batching support from crypto_engine, as there are no drivers using this feature and it doesn't really work that well. Instead of doing batching based on backlog, a more optimal approach would be for the user to handle the batching (similar to how IPsec can hook into GSO to get 64K of data each time or how block encryption can use unit sizes much greater than 4K).
