    Fix database poison warnings, part 19

    The following warning appears in the unit test logs a number of times.

        "UserWarning: This test uses methods that set internal oslo_db
    state, but it does not claim to use the database. This will conflict
    with the setup of tests that do use the database and cause failures
    later."

    This patch fixes all the warnings from:

        nova.tests.unit.virt.ironic.test_driver.py

    Note that this warning is only emitted once per unit test worker, so new
    offenders will show up in the logs each time you fix a test until they
    are all gone.
