Fix pylint warnings in update_device.py
We weren't actually using our own pylintrc file in repo upload hook,
which will be fixed by https://android-review.googlesource.com/#/c/platform/tools/repohooks/+/458996/
Even though both camel case and snake case are allowed for function
and method names, they still have to be consistent in a single file.
