[PATCH libgpiod 2/3] bindings: python: tests: disable device before releasing the bank

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

Linux kernel commit 8bd76b3d3f3a ("gpio: sim: lock up configfs that an
instantiated device depends on") uncovered an issue in Python bindings
tests where the GPIO simulator device is not disabled before removing its
configfs entries. Reorder the operations in chip_finalize() in order to
disable the device first (if needed) before releasing any other
resources.
