usb: dwc3: gadget: Protect against ep disabling during completion
In dwc3_cleanup_done_reqs(), a potential race condition
could arise when dwc3_gadget_giveback() temporarily
releases the main spinlock. If during this window the
very endpoint being handled becomes disabled, it would
lead to a NULL pointer dereference in the code that
follows. Guard against this by making sure the endpoint
is still enabled after returning from the giveback call.
