[PATCH 3.18 118/145] crypto: mcryptd - Fix load failure

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

commit ddef482420b1ba8ec45e6123a7e8d3f67b21e5e3 upstream.

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.
