MODE 6/7 for SCE_UTILITY_SAVEDATA_TYPE_DELETE/LISTDELETE

Tested with following games and also confirm on real PSP to delete save files

* Fate extra
* FF Crisis core

MODE 7 should be SCE_UTILITY_SAVEDATA_TYPE_LISTDELETE which only list valid save while MODE 6 should be SCE_UTILITY_SAVEDATA_TYPE_DELETE which show all save include new save .

Therefore , listEmptyFile should be for LIST operation only which show valid save for load and delete and shouldn't include SCE_UTILITY_SAVEDATA_TYPE_DELETE 

	bool listEmptyFile = true;
	if (param->mode == SCE_UTILITY_SAVEDATA_TYPE_LISTLOAD || param->mode == SCE_UTILITY_SAVEDATA_TYPE_LISTDELETE | )
	{
		listEmptyFile = false;
	}
