Already placed blocks must be flagged as FIXED instead of PLACED. 

* Bug: In cumulus/plugins/block/block.py, when a block is found to have
    a layout, that is, is already placed & routed, it's instances must
    be flagged as FIXED instead or PLACED so Etesian will really sees
    them as unmovable and don't account them to be placed.
