[Xenial][PATCH 2/2] crypto: mcryptd - Fix load failure

[Marcelo Cerri]

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

BugLink: https://bugs.launchpad.net/bugs/1637165

mcryptd_create_hash() fails by returning -EINVAL, causing any
driver using mcryptd to fail to load. It is because it needs
to set its statesize properly.
