Revert "usb: dwc3: gadget: use update transfer command"
This reverts commit 6bb4fe12ea089da98b89dc2630d2273d60fe0c29
("usb: dwc3: gadget: use update transfer command"). If we get
a Xfer Not Ready event with reason "Transfer Active" issuing
update transfer for the endpoint for any pending request
results into transfer stall on the endpoint. Hence do not use
update transfer command for on-demad transfers.
