The event currently only contains the BlockBackend name. However, with anonymous BlockBackends, this is always the empty string. Add the qdev ID (or if none was given, the QOM path) so that the user can still see which device caused the event. Event generation has to be moved from bdrv_eject() to the BlockBackend because the BDS doesn't know the attached device, but that's easy because blk_eject() is the only user of it.
