Currently, the nintendo module needs to maintain hid resources
by itself. Use devm_hid_hw_start_and_open helper to ensure that hid
resources are consistent with the device life cycle, and release
hid resources before device is released. At the same time, it can avoid
the goto-release encoding, drop the err_close and err_stop lables.
