Subject: [PATCH v3 2/3] HID: nvidia-shield: Fix some missing function calls() in the probe error handling path

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

The commit in Fixes updated the error handling path of
thunderstrike_create() and the remove function but not the error handling
path of shield_probe(), should an error occur after a successful
thunderstrike_create() call.

Add the missing calls.

Fixes: 3ab196f88237 ("HID: nvidia-shield: Add battery support for Thunderstrike")

      v2->v3:
        - No changes.
