[CRYPTO]: Cleanups and more consistency checks.

- Removed local_bh_disable() from kmap wrapper, not needed now with
two atomic kmaps.
- Nuked atomic flag, use in_softirq() instead.
- Converted crypto_kmap() and crypto_yield() to check in_softirq().
- Check CRYPTO_MAX_CIPHER_BLOCK_SIZE during alg init.
- Try to initialize as much at compile time as possible
(feedback from Christoph Hellwig).
- Clean up list handling a bit (feedback from Christoph Hellwig).
