crypto: ghash-clmulni - Fix load failure
Wang, Rui Y authored
commit 3a020a72 upstream.

ghash_clmulni_intel fails to load on Linux 4.3+ with the following message:
"modprobe: ERROR: could not insert 'ghash_clmulni_intel': Invalid argument"

After 8996eafd

 ("crypto: ahash - ensure statesize is non-zero") all ahash
drivers are required to implement import()/export(), and must have a non-
zero statesize.

This patch has been tested with the algif_hash interface. The calculated
digest values, after several rounds of import()s and export()s, match those
calculated by tcrypt.
