Considering 'id' is mandatory for user_creatable objects/backends and user_creatable_add_type() always has it as an argument regardless of where from it is called CLI/monitor or QMP, Fix issue by adding 'id' property to hostmem backends and set it in user_creatable_add_type() for every object that implements 'id' property. Then later at query-memdev time get 'id' from object directly.
