usb: dwc3: gadget: combine return points into a single one
dwc3_send_gadget_ep_cmd() had three return points. That becomes a pain to track when we need to debug something or if we need to add more code before returning. Let's combine all three return points into a single one just by introducing a local 'ret' variable. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
