[PATCH] HID: nintendo: Add missing array termination

[Guenter Roeck <linux@roeck-us.net>]

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.

Fixes: 2af16c1f846bd ("HID: nintendo: add nintendo switch controller driver")
