usb: dwc3: clean TRB if STARTTRANSFER fail
In case STARTTRANSFER will fail, clean TRB.
Seems HW in such case don't clean HWO bit.
So, without this cleanup prev_trb still have
HWO bit set.
In my case (without patch), after first START failed:
- dep->enqueue == 1
- dep->dequeue == 1
- prev_trb still have HWO set
- left_trb() == 0
No way to send more data.
