I think it should actually be

	b6d972f6898308fbe7e693bf8d44ebfdb1cd2dc4
	crypto: af_alg/hash: Fix recvmsg() after sendmsg(MSG_MORE)

Anyway, I think we should fix it by adding a new goto label that
does not free the SG list:

unlock_free:
	af_alg_free_sg(&ctx->sgl);
<--- Add new label here
	hash_free_result(sk, ctx);
	ctx->more = false;
	goto unlock;

Thanks,
