usb: chipidea: udc: improve error recovery for ISO transfer
Impove device mode ISO transfer error tolerant by reprime the corresponding
endpoint.
The recovery steps when error occurs:
- Delete the error dTD from dQH and giveback request to user.
- Do reprime if dQH is not empty.
- Do prime when new dTD is queued if dQH is empty
