core: Improve performance of updateAllDiskImageDynamicWithDiskIdByVmId

updateAllDiskImageDynamicWithDiskIdByVmId is running an update on the
disk_image_dynamic table, using a subquery on the images table.
Since images table does not have an index on image_group_id, and images
can be a rather big table, this patch adds such an index.
