    Make sure that we always have a parent_addr set
    
    Since enabling PF tracking in the following commit:
    
    50355c4595e08f293f610da32247e405b20c1c5b
    
    we expect all of the PciDevice objects to have a parent_addr field
    set since we use it for matching in case the (miss-)feature of allowing
    to specify a PF address to enable all VFs was used in the whitelist.
    
    This caused a lazy-load on the object which always fails, so this patch
    makes sure that 'parent_addr' field is set to None on the object even if
    it was not passed in by the driver.
