crypto: cryptd - Assign statesize properly

Browse Source 
commit 1a07834024dfca5c4bed5de8f8714306e0a11836 upstream.

cryptd_create_hash() fails by returning -EINVAL.  It is because after
8996eafdc ("crypto: ahash - ensure statesize is non-zero") all ahash
drivers must have a non-zero statesize.

This patch fixes the problem by properly assigning the statesize.
