BACKPORT: usb: dwc3: gadget: Bail out in pullup if soft reset timeout happens

If the core soft reset timeout happens, avoid setting up event
buffers and starting gadget as the writes to these registers
may not reflect when in reset and setting the run stop bit
can lead the controller to access wrong event buffer address
resulting in a crash.
