usb: dwc3: ep0: fix setup_packet_pending initialization
It just ocurred to me that dwc3 already gives a really hint of when a setup packet is pending and that's the SETUP_PENDING TRB Status for EP0 IRQs. Fix setup_packet_pending initialization based on that. While at that, also make sure the comment in gadget.c matches what code is doing. Signed-off-by: Felipe Balbi <balbi@ti.com>
