wm: invalidate dataspaces on model updates

Browse Source 
If the Rom_session::update function returns false, the ROM dataspace may
have been physically destructed (and core has removed all mappings).
In this case, we have to omit the detach operation in the destructor
of 'Attached_dataspace' to avoid detaching the same region twice.
