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.

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.

In doing so it did not maintain the proper ordering, thus resulting in potential state corruption where the child will overwrite the state stored by cryptd.
