crypto: cryptd - Assign statesize properly

commit 1a078340 upstream.

cryptd_create_hash() fails by returning -EINVAL.  It is because after
8996eafd ("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.
