usb_hid: Allow USB work to progress while waiting for tud_hid_ready
Otherwise, examples like the one attached to the related issue fail because tud_hid_ready never returns true. Testing performed: Adapted the example to nrf particle xenon (it was handy), removed dependency on IR, verified that the problem occurred before this change, and that it was fixed after this change. Closes: adafruit#2048
