From: Rahul Rameshbabu
Date: Mon Sep 18 2023 - 07:59:29 EST


From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

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.
