USB: gadgetfs race fix

This resolves a race in gadgetfs associated with changing device/ep0
when processing control requests.  The fix is to change that state
earlier, when the control response is issued, so there's no window
in which userspace could see the wrong state; and enlarge the scope
of the spinlock during the ep0 request completion handler.
