Crypto hash algorithms must provide the statesize for
kernel 4.2+
Referencing commit in the kernel:
commit 8996eafdcbad149ac0f772fb1649fbb75c482a6a

crypto: ahash - ensure statesize is non-zero
Unlike shash algorithms, ahash drivers must implement export
and import as their descriptors may contain hardware state and
cannot be exported as is. Unfortunately some ahash drivers did
not provide them and end up causing crashes with algif_hash.
This patch adds a check to prevent these drivers from registering
ahash algorithms until they are fixed.
