[PATCH 2/2 T/U/X SRU] crypto: cryptd - Assign statesize properly

From: "Wang, Rui Y" <rui.y.wang at intel.com>

BugLink: http://bugs.launchpad.net/bugs/1633058

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.
