While this is a worthwhile improvement, I don't think it's a bug
fix.  The only error that can actually happen is if you call
memcpy_tosglist from hard IRQ context.

Since there isn't any such usage in the current kernel, this is
purely an enhancement.

So I will be putting this into cryptodev and not crypto.

Thanks,
