static executor: Ignore errors while removing addresses

Browse source 
When having multiple addresses set from the same prefix they might/will(?)
  be configured as 'secondary' and implicitly removed when removing the
  non-secondary address. This leads ip complaining about not being able
  to remove the secondaries as they are already gone. So we ignore errors
  while deconfiguring addresses as they liked occur when removing a
  vanish address anyway.
