Now that the TRB reclaim logic always inspects the TRB's CHN (Chain) bit directly to determine whether a TRB is part of a chain, the explicit 'chain' parameter passed into dwc3_gadget_ep_reclaim_completed_trb() is no longer necessary.
This cleanup simplifies the reclaim code by avoiding duplication of chain state tracking, and makes the reclaim logic rely entirely on the hardware descriptor flags — which are already present and accurate at this stage.
No functional changes intended.
