Subject: [PATCH] action: Only unmount /vendor if it actually exists

* Since commit 168bc4caaedfdf655a71ba24a1c5a7f2b905a122 the vendor partition gets unmounted prior to switching the slots. However, devices without a vendor partition (e.g. tissot's stock partition table) will have errors since the partition doesn't actually exist
* Therefore, it should be only mounted if that partition exists in the partition table
