    Make test_poll_volume_usage_with_data more reliable

    This test includes 2 calls to time.time(). It assumes that the result
    from the second call may be greater than the first. This isn't
    definietly true and we see periodic failures of this test in the gate as
    a result.

    Change the test to not worry about the specific time value that gets
    set. We set _last_vol_usage_poll to 0 before calling the function under
    test. We really only need to check that it got set to some value after
    calling the function under test. This tweak should make the test pass
    consistently.
