core: remove io_mem attachments before destruction

Browse Source 
The attachment removal is triggered actually on _ds member destruction time,
but after the io_mem representation for the specific base-<platform> possibly
vanished already during _unmap_local in the ~Io_mem_dataspace. This creates
on base-sel4 several kernel warnings about invalid capabilities.

Issue #4913
