Thinh Nguyen f06b7e6a77 usb: dwc3: gadget: Clear ep descriptor last
[ Upstream commit f90f5afd5083a7cb4aee13bd4cc0ae600bd381ca ]

Until the endpoint is disabled, its descriptors should remain valid.
When its requests are removed from ep disable, the request completion
routine may attempt to access the endpoint's descriptor. Don't clear the
descriptors before that.
