If a fail device or a spare is removed from an array, there is not need to make the array 'active'. If/when the array does become active for some other reason the metadata will be update to reflect the removal. If that never happens and the array is stopped while still read-auto, then there is no loss in forgetting the that the device had 'failed'. A read-only array will leave failed devices attached to the array personality, so we need to explicitly call remove_and_add_spares() to free it (clearing Blocked just like we do in store_slot()).
