[PATCH] hwmon: nzxt: Fix some error handling path in kraken2_probe()

From: Christophe JAILLET
Date: Sun Dec 03 2023 - 10:24:24 EST


There is no point in calling hid_hw_stop() if hid_hw_start() has failed.
There is no point in calling hid_hw_close() if hid_hw_open() has failed.

Update the error handling path accordingly.
