    elf: Fix a DTV setup issue [BZ #27136]
    
    The max modid is a valid index in the dtv, it should not be skipped.
    
    The bug is observable if the last module has modid == 64 and its
    generation is same or less than the max generation of the previous
    modules.  Then dtv[0].counter implies dtv[64] is initialized but
    it isn't. Fixes bug 27136.
