> Move the hardware-LLP residue calculation into
> dwc_get_hard_llp_desc_residue() so it can be reused independently of
> completion handling.
>
> Keep the scanner's LLP snapshot, descriptor updates and early returns
> unchanged. The helper reports whether it found the current descriptor,
> including when that descriptor has zero residue, rather than using the
> residue value as a completion indication.
