usb: dwc3: gadget: issue ENDTRANSFER conditional on resource_index

Browse source

Because of recent changes to transfer handling on
DWC3, we will not get XferComplete unless we
completely fill up our TRB ring. This means that we
might get a Reset or Disconnect without getting a
XferComplete first.

In order to correctly release our allocated Transfer
Resource, we must issue ENDTRANSFER command whenever
dep->resource_index is valid.
