[PATCH 5.18 0020/1095] HID: nintendo: Add missing array termination

From: Guenter Roeck <linux@roeck-us.net>

commit ab5f3404b7762b88403fbddbdda6b1b464bd6cbc upstream.

joycon_dpad_inputs_jc[] is unterminated. This may result in odd warnings
such as

input: input_set_capability: invalid code 3077588140 for type 1

or in kernel crashes in nintendo_hid_probe(). Terminate the array to fix
the problem.
