Subject: [PATCH] crypto: n2: add missing hash statesize

Add missing statesize to hash templates.
This is mandatory otherwise no algorithms can be registered as the core
requires statesize to be set.

CC: stable@...nel.org # 4.3+
Reported-by: Rolf Eike Beer <eike-kernel@...tec.de>
Tested-by: Rolf Eike Beer <eike-kernel@...tec.de>
Fixes: 0a625fd2abaa ("crypto: n2 - Add Niagara2 crypto driver")
