    Commit usage decrement after destroying instance

    This fixes a regression in Ocata where we were always
    decrementing quota usage during instance delete even
    if we failed to delete the instance. Now the reservation
    is properly committed after the instance is destroyed.

    The related functional test is updated to show this working
    correctly now.
