dtc: fix for_each_*() to skip first object if deleted
The previous definition of for_each_*() would always include the very first object within the list, irrespective of whether it was marked deleted, since the deleted flag was not checked on the first object, but only on any "next" object. Fix for_each_*() to check the deleted flag in the loop body every iteration to correct this.
