USB: UDC: Implement udc_async_callbacks in dummy-hcd
This patch adds a udc_async_callbacks handler to the dummy-hcd UDC
driver, which will prevent a theoretical race during gadget unbinding.
The implementation is simple, since dummy-hcd already has a flag to
keep track of whether emulated IRQs are enabled. All the handler has
to do is store the enable value in the flag, and avoid setting the
flag prematurely.
