Subject: Crypto Fixes for 4.15

Hi Linus: 

This push fixes the following issues:

- Fix chacha20 crash on zero-length input due to unset IV.
- Fix potential race conditions in mcryptd with spinlock.
- Only wait once at top of algif recvmsg to avoid inconsistencies.
- Fix potential use-after-free in algif_aead/algif_skcipher.
