Several of the algorithms in marvell/hash.c have a statesize of zero.
When an AF_ALG accept() on an already-accepted file descriptor to
calls into hash_accept(), this causes:
char state[crypto_ahash_statesize(crypto_ahash_reqtfm(req))];
to be zero-sized, but we still pass this to:
err = crypto_ahash_export(req, state);
which proceeds to write to 'state' as if it was a "struct md5_state",
"struct sha1_state" etc. Add the necessary initialisers for the
.statesize member.
