Title: MODE 6/7 for SCE_UTILITY_SAVEDATA_TYPE_DELETE/LISTDELETE

Tested with following games and also confirm on real PSP

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 as @xele2 mentioned .
