usb: dwc3: gadget: Fix desc NULL pointer in dwc3_gadget_ep_queue()
dep->endpoint.desc is checked at the beginning of
dwc3_gadget_ep_queue(), but after that it may be set to NULL
by another thread and then accessed again in dwc3_gadget_ep_queue().
This will lead to kernel oops.
Expand spinlock protection area to aviod race condition.
