usb: dwc3: gadget: reset resource index to zero
If we collected two requests together (i.e. only the last of them has LST=1) then we only have to stop transfer once: The clean-up code will cleanup everything until first TRB with the LST bit set. After XferComplete this index should be no longer valid since there is no transfer pending. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
